Like this, in present vacuum insulation material, mainly glass fibre is used as core.But, because glass fibre is hard and crisp, so, when making vacuum insulation material, exist if dust disperses, mucocutaneous etc. attached to the operator, the possibility that then is upset, its property handled, operation property become problem.

In addition, under the situation about seeing from the viewpoint of utilizing again, for example with regard to refrigerator, utilizing factory to be pulverized again by every kind of goods.At this moment, glass fibre is entrained in polyurethane bits etc., supplies to heat and utilizes.Glass fibre exists descends combustion efficiency, or becomes residue etc., the more not good problem of usability.

On the other hand, with the parts that polyester fibre uses as core, the property handled, usability is excellent again.But the parts that polyester fibre is used as core are that the pyroconductivity as the index of expression heat-shielding performance is (for example, referring to a patent documentation 7) about 0.0030 [W/mK].The parts that polyester fibre is used as core with glass fibre is compared as the general vacuum insulation material (about pyroconductivity 0.0020 [W/mK]) of core use, have the shortcoming of heat-shielding performance difference.

Therefore, can also make the layer attenuation of organic fiber, make the orientation of fiber vertical, improve heat-shielding performance with the heat transfer direction.But so, the lamination number is more than hundreds of is opened, and productivity worsens.In addition, bending also is difficult to bending because of the lamination number more, and the property handled productivity worsens.

In addition, in the packaging material, that inner pressure relief is airtight outside cores such as glass fibre being inserted aluminium foil laminated film etc.; Make under the situation of vacuum insulation material, under the situation outside core being inserted aluminium foil laminated film etc. in the packaging material, especially under the situation of having used inorfils such as glass fibre; Exist glass fibre that outer packaging material is pricked and pass through, damage or stave the possibility of outer packaging material, the core with glass fibre does not directly insert in the outer packaging material; But outside the state of the bag that is inserted into split such as Polythene Bag inserts down packaging material, need Polythene Bag etc. extraly, the manufacturing process of core, the vacuum insulation material complicacy that becomes; In addition, cost raises.

In addition, also consider, to form folding line through the sheet parts (waste paper) of continuous band shape are alternately turned back at different direction as patent documentation 9; Make it overlapping mode and carry out lamination; Form the situation of core, still, need to form the device that folding line is turned back; The complex structure of this device of turning back and valency are high, and cost raises.

In addition, under the situation for the vacuum insulation material that glass fibre is used for core, the glass fibre heat-shielding performance is excellent.But, because glass fibre is hard and crisp, so, after vacuum, be difficult to carry out bending.

In addition, under the situation of the vacuum insulation material that glass fibre is used for core, the glass fibre heat-shielding performance is excellent.But, because glass fibre is hard and crisp, so, to carry out heat insulationly between vacuum insulation material and the vacuum insulation material even desire is clipped in pipe arrangements such as condensation tube, piping shape can not be out of shape, and between vacuum insulation material, has the gap with the corresponding amount of diameter of pipe.Therefore, produce heat leak from the gap between vacuum insulation material, heat-shielding performance significantly worsens.

In addition, organic fiber being used under the situation of core, a plurality of individual sheet materials being carried out lamination when making core, also is that the lamination number of vacuum insulation material is many more hard more.Therefore, under the situation of the laggard line bend processing of vacuum, exist to be difficult to, and connect the problem of not thinking that crooked part can deform in the crooked part bending of needs.

The present invention is the invention of making for the problem that solves above-mentioned that kind, with provide a kind of have at least following shown in characteristic any one vacuum insulation material core manufacturing installation and vacuum insulation material production method and vacuum insulation material and used the refrigerator of this vacuum insulation material to be purpose.

(1) heat-shielding performance is good, productivity (the especially productivity of core) excellence.

(2) heat-shielding performance is good, and the property handled, usability is excellent again.

(3) used under the situation of organic fiber aggregate at core, productivity is excellent.

(4) can make core with the crooked size of bending with matching, and easy to manufacture.

Embodiment

Mode of execution 1.

Fig. 1 to Fig. 4 is the figure of expression mode of execution 1; Fig. 1 is the schematic representation of vacuum insulation material 7, the stereogram of the core 5 of the vacuum insulation material 7 of a plurality of nonwoven fabric sheets that are lamination, and Fig. 2 is the schematic representation of vacuum insulation material 7; It is the side view of the orientation of the fiber in nonwoven fabric sheet of expression; Fig. 3 is the schematic representation of vacuum insulation material 7, is the side view of directed situation of the fiber of the situation of expression core 5 with thickness, and Fig. 4 is the exploded perspective view of the structure of expression vacuum insulation material 7.

(stromatolithic structure)

In Fig. 1, core 5 for example have sheet organic fiber aggregate (calling " organic fiber aggregate 1 " in the following text) lamination that cut at least one end face 1a stromatolithic structure.That is, core 5 shown in Figure 1 forms after OBL organic fiber aggregate 1 roughly is a plurality of by lamination, the sheet that roughly rectangular four limits have been cut.Perhaps, a plurality of after four limits of roughly OBL organic fiber aggregate 1 are cut by lamination, form roughly rectangular sheet.

In Fig. 2, organic fiber aggregate 1 open by sky regulation compartment of terrain configuration many organic fiber 2x and with organic fiber 2x roughly the direction sky of quadrature many organic fiber 2y opening the compartment of terrain configuration of regulation form.

At this moment, organic fiber 2x roughly puts with organic fiber 2y and contacts.Between organic fiber 2y, form air layer 3 as insulated space.

Be generically and collectively referred to as organic fiber 2 as organic fiber 2x and organic fiber 2y.

Here, as shown in Figure 3, if the thickness of a sheet material (organic fiber aggregate 1) thickens, then fiber is easily to be directed towards the mode as the thickness direction of heat transfer direction.Especially be under the situation of the short short fibre (length of staple for example is about 5～150mm) of length of staple at organic fiber 2 (situation that simply is called fiber is also arranged), short fibre is easily to be directed towards the mode as the thickness direction of heat transfer direction.Heat is transmitted (representing with arrow Fig. 3) from the table side direction of sheet material is inboard through this short fibre, and heat-shielding performance worsens.

Therefore,, make the sheet of thin thickness, can suppress fiber orientation heat transfer direction (thickness direction of the organic fiber aggregate 1 of the stack direction of the fiber of organic fiber aggregate 1, sheet) orientation through organic fiber aggregate 1 lamination must be approached.In view of the above, can suppress heat in fiber transmission, the situation that heat-shielding performance reduces towards heat transfer direction orientation.Therefore, can make the pyroconductivity of core 5 little, can improve heat-shielding performance.

In Fig. 2, solid arrow and dotted arrow are represented the direction of transfer of heat.Because organic fiber 2x and organic fiber 2y be quadrature roughly, so the contact segment of organic fiber 2x and organic fiber 2y contacts for point, thermal resistance increases, and heat-shielding performance improves.

In addition, represented the mutual roughly situation of quadrature of organic fiber 2x and organic fiber 2y above, but this mode of execution is not limited thereto.Also can be that organic fiber 2x and organic fiber 2y are each other with the angle of intersection of non-right angle.All organic fiber 2x and organic fiber 2y get final product so long as not configuration abreast.If can be suppressed at slightly towards the directed fiber of heat transfer direction and transmit heat, the situation that heat-shielding performance is low then can improve heat-shielding performance.

In Fig. 4, vacuum insulation material 7 comprises the airbond property container (calling " outer packaging material 4 " in the following text) with air property cut off, core 5 and the sorbent 6 (for example, adsorbent, moisture adsorbent (CaO) etc.) of being enclosed the inside of outer packaging material 4.And the inside of outer packaging material 4 is depressurized to specified vacuum degree (about several Pa (Pascal)～hundreds of Pa).

(organic fiber)

Organic fiber 2 employed materials as the core 5 that forms vacuum insulation material 7 can use polyester, polypropylene in addition, PLA, aromatic copolyamide, LCP (liquid-crystalline polymer), PPS (polyphenylene sulfide), polystyrene etc.In addition, under the situation that the heat resistance of wanting to make core 5 improves, organic fiber 2 is as long as use LCP (liquid-crystalline polymer), PPS (polyphenylene sulfide) etc. to have stable on heating resin.In addition, wanting to make under the situation of compression creep characteristic raising, needing only and use the big material in fiber footpath.In addition, if above-mentioned mixed with resin is used, then can access the heat resistance height and the high vacuum insulation material 7 of thermal insulation of compression creep excellent.Polystyrene solid thermal conductivity is little, can expect to improve the heat-shielding performance of heat insulation material, and can make at an easy rate.

Polypropylene is low because of hygroscopicity, and can shorten time of drying, the pumpdown time, can boost productivity.In addition, polypropylene is little because of solid thermal conduction, so, can expect to improve the heat-shielding performance of vacuum insulation material 7.

In addition, because PLA has biological degradability, so after using goods, the core that is disintegrated, classifies can also carry out landfill disposal.

In addition, aromatic copolyamide, LCP be because rigidity is high, so, having by vacuum-packed, the shape retention when having received barometric pressure is good, can improve voids, can expect to improve advantages such as heat-shielding performance.

Core 5 is the vacuum insulation material 7 of packaging material 4 outside composite plastic film is used for for example, bears the supporting barometric pressure, guarantees the effect in the space in the vacuum insulation material 7 and cuts apart the space is trickle, reduces the effect of the transmission of heat etc. of gas.In addition, from suppressing the heat conducting viewpoint of gas, hope to make the distance in this space littler than the free travel distance of the air molecule under its degree of vacuum.

In this mode of execution, because the core 5 of vacuum insulation material 7 for example uses organic fiber 2, so; Compare as the situation that core is used with such hard and crisp glass fibre in the past; Can also eliminate when making vacuum insulation material 7, dust disperses, mucocutaneous etc. attached to the operator; Stimulate such situation, the property handled, the raising of operation property.

(production method of fiber assembly raw material (grey cloth reel raw material))

With regard to the organic fiber aggregate 1 (the organic fiber aggregate is identical with the sheet aggregate) that forms core 5; Heating and melting resin such as polyester resin, polystyrene resin from respect to the width of wanting to make; Several nozzles that are arranged in horizontal row freely fall on conveyer, and one side makes conveyer with speeds arbitrarily, and one side is pressurizeed by compression roller; Be wrapped in grey cloth cylindraceous with on the roller, make grey cloth reel raw material roughly cylindraceous.The volume density of organic fiber aggregate 1 can access the different fiber assembly of thickness according to the discharge capacity of melting resin and the speed adjustment of conveyer.

In addition; With regard to regard to the nonwoven fabric of long fibers of organic fiber aggregate 1; Through making it fusion and trap on the conveyer by extrusion press from the continuous fiber of spinning-nozzle extruding, make conveyer with speed feeding arbitrarily, form sheet; In view of the above, obtain to be wound into grey cloth with the continuous nonwoven fabric of long fibers on the roller.Because can access the organic fiber aggregate 1 of the continuous sheet that forms by continuous organic fiber 2, so, can be wrapped in grey cloth cylindraceous continuously with on the roller, can access the grey cloth reel of nonwoven fabric of long fibers.

In addition, spinning can use under the nozzle with resin with cooling such as cold wind after, extend by pressurized air etc., the high temperature air that carry out Fibrotic method, is equal to from the nozzle bore next door with the melt temperature with resin brushes, and carries out Fibrotic method.

In addition, inconsistent each other through the organic fiber aggregate 1 that above-mentioned method obtains owing to organic fiber 2, so, there is the not good situation of processing property when making vacuum insulation material 7.Therefore, also can when pressurization, organic fiber 2 be added hot melt each other apply.At this moment, excessive pressurization, add hot melt and apply the area of contact cause between the organic fiber 2 and increase, the increase of heat transfer produces the transmission of heat that begins from melt-coating part, causes the reduction of heat-shielding performance.Therefore, should make the area of contact between the organic fiber 2 little as far as possible.Area of contact between the organic fiber 2 hopes to be suppressed at below 20% of whole area (sheet material area), preferably below 15%, more preferably below 8%.

Because can confirm as if add that hot melt applies shared ratio and surpasses 20% of whole area (sheet material area), then pyroconductivity becomes big, the heat-shielding performance variation, so, still preferably make to add the deposited shared ratio of hot melt at below 20% of whole area (sheet material area).Here; Because add hot melt and apply shared ratio and reduce if make with respect to whole area (sheet material area); Then heat-shielding performance further improves; So hope will add the deposited shared ratio of hot melt and be suppressed at below 15% of whole area (sheet material area), and then be suppressed at below 8% of whole area (sheet material area).

Just adding with regard to hot melt applies, is through forming the for example embossing processing of the melt-coating part of point-like by hot-rolling etc., obtain guaranteeing to handle intensity, and the good nonwoven fabric of long fibers (organic fiber aggregate 1) of the heat-shielding performance that can twine.In addition, in this mode of execution, the temperature of hot-rolling is about 195 ℃ and gets final product.

Here, though also can be to substitute to add hot melt and apply, vertically prick or mention through a plurality of pins that make buckle times without number; Fiber is tangled each other; And each other can consistent mode become the needle punching of sheet with fiber, still because still through add hot melt apply (for example embossing processing) form the situation of sheet can be corresponding with simple equipment; Operation on conveyer is also easy, so good.

(fiber footpath)

In this mode of execution 1, as fiber assembly, for example, use organic fiber aggregate 1, still, the fiber of this organic fiber aggregate 1 footpath is directly adjusted according to its nozzle of shaping, is written treaty 15 μ m.Should fiber aspect heat-shielding performance the footpath thinner.In theory, fiber footpath should be little from the relation of the free travel distance of the space length that broken up by the internal vacuum of vacuum insulation material 7 and fiber finer, gas molecule.Fiber is directly hoped below 15 μ m, below the preferred 10 μ m, directly is the fiber assembly about 9 μ m as long as use average fiber.

The mensuration in average fiber footpath uses mean value to get final product as long as use the several positions of measurement microscope～tens positions (for example ten positions).In addition, weight per unit area (every 1m ²The weight (g) of fiber) as long as measure the area and the weight of a sheet material, obtain as the weight of the per unit area of a sheet material and to get final product.

In this mode of execution, in the direction that becomes approximate vertical with respect to thickness direction as heat insulation direction, the orientation direction of adjustment fiber, the multi-ply construction of making overlapping a plurality of organic fiber aggregates 1.

In addition, if organic fiber aggregate 1 uses staple fiber nonwoven fabric, then because the length of fiber is short, so organic fiber 2x, organic fiber 2y are directed to heat insulation direction (thickness direction of sheet material) easily.In order to suppress heat in the fiber transmission that is directed to heat insulation direction, heat-shielding performance reduces, and makes and has used long stapled nonwoven fabric of long fibers.

In this mode of execution, because the length of fiber is used and the length of sheet material roughly is equal to above length, so fiber interrupts in the way of sheet material, the part of fiber (in the way), end are difficult to be directed in heat insulation direction, and heat-shielding performance is reduced.

(laminating method of fiber assembly, the production method of core 1)

Then, so that the organic fiber aggregate 1 of resulting sheet for example becomes the mode of the size (width 210mm * length 297mm) of regulation end face 1a is cut (severing).With their lamination multilayers (for example 25 layers), form the size of the regulation that end face 5a has been cut and the core 5 of thickness.Core 5 also can with end face 5a cutting, form the size of regulation behind organic fiber aggregate 1 lamination with a plurality of sheet.In addition, the number of lamination can be that the basis is at random set with the thickness of resulting organic fiber aggregate 1 and the thickness of the vacuum insulation material of wanting to make 7 also.

(outer packaging material)

Outer packaging material 4 (Fig. 4) used thickness of vacuum insulation material 7 more than 5 μ m, the laminated film below the 100 μ m.In this mode of execution, for example use the composite plastic film that constitutes by nylon (6 μ m), aluminium-vapour deposition PET (PETG) (10 μ m), aluminium foil (6 μ m), high density polyethylene (HDPE) (50 μ m) with airbond property.

If in addition the outer packaging material 4 of vacuum insulation material 7 uses the laminated film that does not contain aluminium foil of polypropylene, polyvinyl alcohol, polyacrylic formation etc., the reduction of the heat-shielding performance that then can suppress to cause because of heat bridge.In addition, three limits in four limits of outer packaging material 4 are by closures installation heat-sealing.Remaining one side is resealed after core 5 is inserted.

(production method 1 of vacuum insulation material)

The manufacturing of vacuum insulation material 7 is outer packaging materials 4 that the core 5 of the size that at first will stipulate and thickness inserts the bag shape with opening portion 4a; Fix with the not pent mode of opening portion 4a; Under about 105 ℃ temperature, carry out (about 12 hours) drying on the half at thermostatic bath.After this; To be used to adsorb survival gas after the vacuum packaging, emitted to sequential property from the degassing of core 5, outside packaging material 4 confined bed through and the sorbent 6 (adsorbent, moisture adsorbent etc.) that sees through gas that gets into insert in the outer packaging material 4 (film bag), by cypress formula vacuum package machine (NPC corporate system; KT-650) vacuumize (reduced pressure treatment).Vacuumize and be performed until that degree of vacuum is about 1～10Pa in the chamber, like this in the chamber with the opening portion 4a heat-sealing of outer packaging material 4 (film bag), obtain tabular vacuum insulation material 7.

(laminating method of fiber assembly, the production method of core 2)

Though can be as above-mentioned, the organic fiber aggregate 1 of sheet is cut into many of size and the laminations of regulation, form core 5; Make vacuum insulation material 7, also can be behind organic fiber aggregate 1 lamination with a plurality of sheet, cutting end face 5a; Form the size of regulation, form core 5, make vacuum insulation material 7; But other the production method to core 5 describes here.To the fiber assembly (for example, organic fiber aggregate 1) that twines continuous sheet continuously, the method for making core 5 describes.

Fig. 5, Fig. 6 are the figure of expression mode of execution 1; Fig. 5 is the stereogram of layer-by-layer state of schematically representing to form the core 5 of vacuum insulation material 7, and Fig. 6 is to the grey cloth roller of the laminated device of the core 5 that forms vacuum insulation material 7 and the stereogram that the coiling frame is schematically represented.

Among Fig. 5, Fig. 6; Form by continuous fiber (for example, organic fiber 2), (for example, the organic fiber aggregate 1 for continuous sheet fiber assembly 1J; Thickness is more than about 30 μ m; Below about 500 μ m, more than the preferred 80 μ m, below the 300 μ m) be wrapped in coiling frame 1311 backs (being wound on coiling frame 1311 backs continuously) at tension force and be shaped as planar with regulation; Make core 5, even excessively extension is not enough as the necessary characteristic of fiber thereby the tension force of afore mentioned rules prevents in twining the way, to be cut off or not to be cut off.That is, core 5 is made up of the stromatolithic structure of the continuous sheet fiber assembly 1J that is twined continuously laterally from the inboard at the continuous sheet fiber assembly 1J of length direction (coiling direction).Here, making the width that is shaped as flat core 5 is H, and making length is L, and making thickness is t (referring to Fig. 5).In addition, end 1Je is finished in the end of the coiling of core 5 end as reeling.

Core 5 is to be wound under the state on the coiling frame 1311 in continuous sheet fiber assembly 1J (the grey cloth reel 1301) continuous several times that will for example be wound onto the width with regulation on the grey cloth roller 1302 roughly cylindraceous (to have twined continuously under the state of stipulated number); Coiling frame 1311 extracted at the axis direction of coiling frame 1311 (with respect to the winding direction roughly axis direction of the running shaft 1315 of 90 degree that staggered), squeeze flat one-tenth planar (sheet) and be shaped being wound into continuous sheet fiber assembly 1J roughly cylindraceous.This flat core 5 is shaped as has continuous a plurality of sheet fiber assembly 1J laminations; The both side ends that forms the plat part 5g (partes glabra) of planar (level and smooth shape) and be formed in respect to the length direction of this plat part 5g (is being reeled along quilt under the winding direction continuum of states because of continuous sheet fiber assembly 1J; So; At the continuous sheet fiber assembly 1J of flat winding direction both end sides by bending; Become the state of coiling), continuous sheet fiber assembly 1J is by the planar of the bent end 5f of the state of bending (bending part) (sheet, level and smooth shape).

At this moment, core 5 to be being shaped as planar, and the state that is closed with the substantial vacuum state of packaging material 4 inherences is issued to the mode of the thickness t of regulation outside, confirms the number of times R that twines to coiling frame 1311.For example; If the thickness t (thickness of the regulation of core 5) of necessity of core 5 is 8mm; The thickness that continuous sheet fiber assembly 1J is one is 80 μ m; Then necessary lamination number is 100 (8mm/80 μ m), and therefore, it is suitable 50 times of 50 amount with continuous sheet fiber assembly 1J that the regulation of the necessity that must twine to coiling frame 1311 is twined number of times R.Because the core of the state (cylindric) that coiling frame 1311 is pulled out 5 flattens; And be configured as planar (sheet); So; The thickness t of core 5 is and the thickness of conduct to suitable number 100 tensors of 50 times the twice of the number of times R of grey cloth reel 1301 coilings that core 5 becomes many continuous sheet fiber assembly 1J by the state of lamination (as 100 laminations of regulation number).

In addition, core 5 necessary width (width of regulation) H is suitably adjusted through the width that is wrapped in the continuous sheet fiber assembly 1J (grey cloth reel 1301) on the grey cloth roller 1302, the width of coiling frame 1311.For example; If the width H (width of regulation) of necessity of core 5 is 1500mm; Then also can be about 1500mm with the width setup of coiling frame 1311 as the width of stipulating; Perhaps liken the bigger width (for example about 1520mm) of 1500mm into the width of regulation to, unnecessary part (two width segments) is cut off.

Fig. 7, Fig. 8 are the figure of expression mode of execution 1; Fig. 7 is the figure of structure of the coiling frame of expression vacuum insulation material manufacturing installation; Fig. 7 (a) is the state of the coiling frame of expression when twining continuous sheet fiber assembly 1J; Fig. 7 (b) be expression be through with twine continuous sheet fiber assembly 1J after; The coiling frame is removed the figure of state of the coiling frame of (removing) situation from continuous sheet fiber assembly 1J, Fig. 8 is the figure that expression will be wrapped in the gripping members that the organic fiber aggregate on the coiling frame of vacuum insulation material manufacturing installation clamps.

In this mode of execution, it is roughly cylindric that coiling frame 1311 for example is, and for example is divided into a plurality of by a plurality of circumference parts 1312 at circumferencial direction.For example, coiling frame 1311 is cut apart by circumference parts 1312a, 1312b, 1312c, 1312d four.Among Fig. 7,, still, circumference parts 1312a, 1312b, 1312c, 1312d are referred to as " circumference parts 1312 " though not shownly go out circumference parts 1312.Here; Circumference parts 1312 near the Zhou Fangxiang substantial middle of each that is split into a plurality of circumference parts 1312a, 1312b, 1312c, 1312d in all sides be respectively equipped with the circumference parts retainer shaft 1316 (circumference parts retainer shaft 1316a, 1316b, 1316c, 1316d) that is connected with the running shaft 1315 of the frame 1311 of reeling, a plurality of circumference parts 1312 are connected the running shaft 1315 that remains on coiling frame 1311 through circumference parts retainer shaft 1316.On the running shaft 1315 of coiling frame 1311, insert the live axle that is connected with by drivings such as motor.

Because be split into a plurality of circumference parts 1312 (in this mode of execution; Be four circumference parts 1312a, 1312b, 1312c, 1312d) at least one circumference parts (in this mode of execution; For at radial direction two circumference parts 1312a, 1312b in opposite directions) being provided with can be in the flexible movable circumference parts retainer shaft 1316 of radial direction (in this mode of execution; Be circumference parts retainer shaft 1316a, 1316b); So; Through after continuous sheet fiber assembly 1J is wrapped in coiling frame 1311; Make circumference parts retainer shaft 1316a, 1316b movable in the direction of shrinking towards the radial direction central side, the tension force that can make tension force with regulation be wound on the continuous sheet fiber assembly 1J on the coiling frame 1311 relaxes roughly cylindricly, can extract at the shaft core direction of running shaft 1315 from the continuous sheet fiber assembly 1J that coiling frame 1311 will twine roughly cylindricly.Promptly; Because the tension force that is wrapped in the continuous sheet fiber assembly 1J on the coiling frame 1311 through the tension force that makes with regulation relaxes; The continuous sheet fiber assembly 1J that will be wrapped in easily on the coiling frame 1311 extracts from coiling frame 1311; So, can not can continuous sheet fiber assembly 1J be extracted easily with damaging.

Here, on coiling frame 1311, at least one position be arranged on extract coiling frame 1311 after, organic fiber aggregate 1 cylindraceous is roughly kept or fixing gripping members 1320.In this mode of execution, gripping members 1320 freely is arranged on circumference parts 1312c, 1312d or the circumference parts retainer shaft 1316c, the last gripping members of 1316d that are separately positioned at least two positions (two positions in opposite directions) by dismounting respectively the 1313c of portion, 1313d is set.In addition; Two gripping memberss are provided with the 1313c of portion, 1313d is set at and can stretches movable circumference parts retainer shaft 1316 (in this mode of execution at radial direction; Be circumference parts retainer shaft 1316a, 1316b) different at different position and different (for example, different circumference parts retainer shaft 1316c, 1316d).

This gripping members 1320 is with under the roughly cylindric state that is wrapped in coiling frame 1311 of continuous sheet fiber assembly 1J; Can continuous sheet fiber assembly 1J be kept or fixing (for example, keeping or fixing through sandwiching) mode between the outer circumferential side of the interior all sides of continuous sheet fiber assembly 1J cylindraceous roughly and coiling frame 1311 is set up.This gripping members 1320 for example is bar-shaped, tabular; Can before twining continuous sheet fiber assembly 1J, begin; Freely be arranged on coiling frame 1311 sides with respect to 1311 dismounting of coiling frame; Also can be to be wrapped under the state on the coiling frame 1311 at continuous sheet fiber assembly 1J; Then, insert between continuous the sheet fiber assembly 1J (interior all sides) and coiling frame 1311 (outer circumferential side) from the axle direction of running shaft 1315, for example the gripping members at two positions (for example is provided with portion 1313; The gripping members that is separately positioned on circumference parts 1312c, 1312d, circumference parts retainer shaft 1316c, 1316d is provided with the 1313c of portion, 1313d) mode be provided with; Keep continuous sheet fiber assembly 1J, portion 1313 (for example, gripping members is provided with the 1313c of portion, 1313d) can also be set with the gripping members at two positions sandwich, keep continuous sheet fiber assembly 1J at two positions.In addition, though among Fig. 8, gripping members is provided with portion 1313 and is not illustrated out,, with gripping members the 1313c of portion is set, 1313d is referred to as " gripping members is provided with portion 1313 ".

Here; In this mode of execution; The circumference parts 1312 that are provided with gripping members 1320 in coiling frame 1311 (for example; At the Immobile circumference parts of radial direction 1312c, 1312d) the setting of outer circumferential face side portion 1313 (recess that for example, is set up with the mode of the width (perhaps length) that for example has regulation towards running shaft 1315 directions, otch etc.) can be set at the gripping members that gripping members was taken in or inserted to the axle direction of the running shaft 1315 of coiling frame 1311.

Taken in or be inserted in gripping members 1320 that gripping members is provided with portion 1313 (for example 1313c, 1313d) for example for bar-shaped, tabular; As long as before continuous sheet fiber assembly 1J is wrapped in coiling frame 1311; Be arranged on gripping members portion 1313 (gripping members is provided with the 1313c of portion, 1313d) is set; After continuous sheet fiber assembly 1J is wound into coiling frame 1311; Can make circumference parts 1312a; 1312b is movable to the central direction (shrinkage direction) of radial direction; After the tension force that will be wrapped in the roughly cylindraceous continuous sheet fiber assembly 1J on the coiling frame 1311 with the tension force of regulation relaxes, continuous sheet fiber assembly 1J is clamped ((gripping members is provided with the 1313c of portion, 1313d) clamping at two positions at least in this mode of execution) with gripping members 1320, extract from coiling frame 1311 then and get final product.

Perhaps; Also can continuous sheet fiber assembly 1J with the regulation tension force by the general cylindrical shape shape be wrapped in coiling frame 1311 after; At least one gripping members 1320 is inserted the Immobile circumference parts 1312c that is set at the coiling frame 1311 between the outer circumferential side of the interior all sides of continuous sheet fiber assembly 1J and coiling frame 1311, recess that the last gripping members of 1312d is provided with portion 1313 (gripping members is provided with the 1313c of portion, 1313d), otch etc. from the axle direction of the running shaft 1315 of coiling frame 1311; Clamp continuous sheet fiber assembly 1J cylindraceous roughly (in this mode of execution; (gripping members is provided with the 1313c of portion, 1313d) clamps at least two positions); Then; Make circumference parts 1312a, 1312b movable to the central direction (shrinkage direction) of radial direction, the tension force that makes tension force with regulation be wrapped in the roughly cylindraceous continuous sheet fiber assembly 1J on the coiling frame 1311 relaxes, and coiling frame 1311 is extracted.

Here; At least one gripping members 1320 (being two gripping members 1320c, 1320d in this mode of execution) freely is set up with respect to 1311 dismounting of coiling frame, is set on Immobile at least one circumference parts (being two circumference parts 1312c, 1312d in this mode of execution) of coiling frame 1311.

Like this; Through making circumference parts 1312a that at least one can be movable, 1312b movable to the tension force direction of relaxing, the tension force that can make tension force with regulation be wrapped in the roughly cylindraceous continuous sheet fiber assembly 1J on the coiling frame 1311 easily relaxes.Therefore; Can not can damage or make a mess of continuous sheet fiber assembly 1J, organic fiber 2 and simply continuous sheet fiber assembly 1J is pulled down from coiling frame 1311; Therefore; Can access simple structure, wind that reliability is high, and, can access low cost, continuous sheet fiber assembly 1J, vacuum insulation material 7 that reliability is high.

Here; The position that continuous sheet fiber assembly 1J is clamped is that the girth of the circumferencial direction of the cross section circle of fiber assembly 1J cylindraceous roughly roughly two is divided into two positions of the position of identical length roughly (sectional shape when the cross section of considering with respect to the axle direction approximate right angle direction of the running shaft 1315 of coiling frame 1311 is (under the situation in general cylindrical shape; Sectional shape is a circular) in, crossing two positions of straight line that the rotating center of the running shaft 1315 of coiling frame 1311 passes through and sectional shape (outer shape in cross section, under for circumference) (two positions of intersecting with circumference under for the situation of circle) for the situation of circle).

Therefore; Because the position that clamps is with the girth of the outer shape in cross section cylindraceous roughly (for being circular under the situation of the general cylindrical shape shape) position at two positions of two five equilibriums roughly; So; Through the state that continuous sheet fiber assembly 1J has clamped is pulled down from coiling frame 1311 by two gripping memberss 1320 (gripping members 1320c, 1320d); Make two gripping members 1320c, 1320d in that roughly straight line side direction in the opposite direction (roughly 180 degree opposite directions) is movable or mobile, repeatedly twined and pulled in opposite direction by two gripping members 1320c, 1320d, therefore by a plurality of continuous sheet fiber assembly 1J of lamination; From the part that is clamped by gripping members 1320c, 1320d, continuous sheet fiber assembly 1J is formed the planar of bending.After this; Through being formed flat continuous sheet fiber assembly 1J from the state with the lamination multilayer, extracts gripping members 1320 (gripping members 1320c, 1320d); It is a plurality of by lamination that continuous sheet fiber assembly 1J keeps continuous sheet; In bent end 5f bending, form the width H of the plat part 5g with flat board (sheet material) shape and the flat core 5 of length L with regulation.

(production method 2 of vacuum insulation material)

Then, according to Fig. 9, the production method of the vacuum insulation material 7 of this mode of execution is described.Fig. 9 is the figure of expression mode of execution 1, is the figure of the production method of expression vacuum insulation material.In Fig. 9, Fig. 9 (a)～(h) is the operation of the manufacturing of expression vacuum insulation material 7.

Fig. 9 (a) begins continuous sheet fiber assembly 1J (organic fiber aggregate 1, the nonwoven fabric sheet for example made by continuous organic fiber 2) to begin step to the coiling that coiling frame 1311 is reeled.Possess through many windings of continuous sheet fiber assembly 1J are formed; And be cut to the grey cloth reel 1301 of the width of regulation, the coiling frame 1311 that winding is wrapped in the continuous sheet fiber assembly 1J on the grey cloth reel 1301 with Rack; Through making grey cloth reel 1301,1311 rotations of coiling frame; The continuous sheet fiber assembly 1J that begins to be wrapped on the grey cloth reel 1301 twines to coiling frame 1311, and this operation is the beginning step of reeling.

Fig. 9 (b) is that continuous sheet fiber assembly 1J is wrapped in stipulated number R on the coiling frame 1311, twines the coiling end step of accomplishing.In the beginning step of reeling; Twine continuous sheet fiber assembly 1J to coiling frame 1311 gradually from grey cloth reel 1301; But, this moment because continuous sheet fiber assembly 1J be wrapped in half the thickness t/2 of predetermined thickness t that thickness a on the coiling frame 1311 (not shown go out) is equivalent to necessity of core 5, so; If twine the amount of the stipulated number R suitable with the thickness a of regulation; Then the rotation of grey cloth reel 1301, coiling frame 1311 stops, and the winding of continuous sheet fiber assembly 1J is accomplished, and this operation is the coiling end step.

Fig. 9 (c) is the cut-out step that continuous sheet fiber assembly 1J (for example, the organic fiber aggregate 1) is cut off.In the coiling end step; Continuous sheet fiber assembly 1J is wrapped in coiling frame 1311, still, because if the number of times R that twines reaches the half the suitable number of times in thickness t/2 with the predetermined thickness t of necessity of core 5; Then the rotation of grey cloth reel 1301, coiling frame 1311 stops; So, be the step that continuous sheet fiber assembly 1J is cut off at the regulation position cutting off step, be place of incision with the continuous regulation of sheet fiber assembly 1J between grey cloth reel 1301 and coiling frame 1311; The state that clamps with the front and back with the place of incision of regulation cuts off, the step that grey cloth reel 1301 is cut off from coiling frame 1311.

Here, the roughly cylindraceous continuous clamped parts 1320 of sheet fiber assembly 1J (gripping members 1320c, 1320d) that are wrapped on the coiling frame 1311 clamp, keep (referring to Fig. 9 (d)).At this moment; To finish end 1Je (cut-out end face) at random or reel and finish end 1Je (cut-out end face) and be configured in bent end 5f (promptly being configured as core 5 time images that kind shown in Figure 5 for the cut coiling that makes the continuous sheet fiber assembly 1J that is wrapped on the coiling frame 1311; Be not positioned at plat part 5g); Hope that (for example, the rear of adjacent clamped position) is cut off continuous sheet fiber assembly 1J in the back position of the position that is clamped by gripping members 1320.

Fig. 9 (d) is the core fixing step that continuous sheet fiber assembly 1J (for example, the organic fiber aggregate 1) cylindraceous is roughly clamped with gripping members 1320.Cutting off step; Continuous sheet fiber assembly 1J is cut off; After this; Gripping members 1320 is inserted into gripping memberss such as the recess that is arranged on the coiling frame 1311, otch portion 1313 (gripping members is provided with the 1313c of portion, 1313d) is set, and to finish end 1Je (cut-out end face) at random or peel off for the coiling that makes continuous sheet fiber assembly 1J, and reeling, it is clamped to finish near the end 1Je (cut-out end face).

Fig. 9 (e) be a plurality of circumference parts of making the Zhou Fangxiang that is arranged on coiling frame 1311 (at least one the circumference parts (1312a, 1312b) among the 1312a～1312d) but at radial direction central direction dynamic deformation, the coiling frame deforming step that the winding tension that is wrapped in the continuous sheet fiber assembly 1J on the coiling frame 1311 is relaxed.In the core fixing step; Clamped near the coiling end end 1Je (cut-out end face); But; In coiling frame deforming step, continuous sheet fiber assembly 1J twines the number of times R of the amount suitable with the thickness (t/2) of regulation to coiling frame 1311, under the state that is clamped by gripping members 1320 (gripping members 1320c, 1320d); (at least one the circumference parts (being at radial direction two circumference parts 1312a, 1312b in opposite directions in this mode of execution) among the circumference parts 1312a～1312d) are towards the radial direction central side of coiling frame 1311, and are movable at shrinkage direction for a plurality of circumference parts 1312 of coiling frame 1311.Promptly; After continuous sheet fiber assembly 1J is wrapped on the coiling frame 1311; Circumference parts retainer shaft 1316a, 1316b are movable at shrinkage direction towards the radial direction central side, and in view of the above, circumference parts 1312a, 1312b are also movable at shrinkage direction towards the radial direction central side.

Therefore; Because it is movable towards the radial direction central side at shrinkage direction through circumference parts 1312a, 1312b; The tension force that is wrapped in the continuous sheet fiber assembly 1J on the coiling frame 1311 with the tension force of stipulating relaxes roughly cylindricly; So, can from coiling frame 1311 easily will twine roughly cylindricly continuous sheet fiber assembly 1J extract (can clamped continuous sheet fiber assembly 1J be extracted easily) from the shaft core direction of the running shaft 1315 of coiling frame 1311.Promptly; Through will with the regulation tension force be wrapped on the coiling frame 1311 continuous sheet fiber assembly 1J (for example; Organic fiber aggregate 1) tension force relaxes, and the continuous sheet fiber assembly 1J that is wrapped on the coiling frame 1311 extracts from coiling frame 1311 easily.

Fig. 9 (f) extracts coiling frame 1311 from the continuous sheet fiber assembly 1J that is wrapped on the coiling frame 1311, the coiling frame separating step that the coiling frame is separated from continuous sheet fiber assembly 1J cylindraceous roughly.In coiling frame deforming step; Because at least one circumference parts 1312 of coiling frame 1311 ( circumference parts 1312a, 1312b) but to radial direction central side dynamic deformation; The tension force that produces because of winding that is wrapped in the continuous sheet fiber assembly 1J on the coiling frame 1311 relaxes; So at coiling frame separating step, the roughly cylindraceous continuous sheet fiber assembly 1J that tension force has been relaxed extracts at the axis direction of running shaft 1315 from coiling frame 1311.Perhaps, also can coiling frame 1311 kept the state that has clamped from continuous sheet fiber assembly 1J cylindraceous roughly extracts.

To be the roughly cylindraceous continuous sheet fiber assembly 1J that will have been separated with coiling frame 1311 by gripping members 1320 (gripping members 1320c, 1320d) as molded component pull the core forming step of the flat core 5 that is shaped to opposite direction (in the other direction) roughly to Fig. 9 (g).At coiling frame separating step; Continuous sheet fiber assembly 1J separates with the state that the gripping members 1320 that is used as molded component clamps from coiling frame 1311; But; In the core forming step; Because through two gripping members 1320c, 1320d are dragged to the opposite direction layback respectively in straight line side in the opposite direction roughly; Continuous sheet fiber assembly 1J roughly cylindraceous is folded at the clamped position as the gripping members 1320 of molded component, so the roughly cylindraceous continuous sheet fiber assembly 1J that extracts with the state that is clamped by two gripping members 1320c, 1320d from coiling frame 1311 is shaped as the core 5 of the planar (sheet) with bent end 5f and plat part 1311g.Clamping under the state of bent end 5f by two gripping memberss 1320 by be configured as the core 5 that flat continuous sheet fiber assembly 1J constitutes through gripping members 1320 as molded component; Be transferred on the conveyer 1400, through gripping members 1320 being removed and being formed as core 5.Promptly; The continuous sheet fiber assembly 1J (for example, the organic fiber aggregate 1) of the continuous planar (sheet) that is formed by continuous fiber (for example, organic fiber 2) reels from the inboard laterally continuously; Form, make flat core 5, on conveyer 1400, move.

Fig. 9 (h) is after the core that is formed on the conveyer 1,400 5 is inserted into the outer packaging material 4 of airbond property of the opening portion 4a with an end opening, and the state that is depressurized in inside is made the vacuum insulation material manufacturing step of vacuum insulation material 7 by roughly sealing.With continuous sheet fiber assembly 1J lamination multilayer; And continuous reeling is formed in the outer packaging material 4 of airbond property that flat core 5 is inserted into the opening portion 4a with at least one end opening laterally from the inboard, is moved in the vacuum furnace, under the substantial vacuum state; The closure of outer packaging material 4 (for example; Opening portion 4a) is resealed, in view of the above, accomplishes vacuum insulation material 7.

Here; Because the circumference parts 1312 of coiling frame 1311 are at the roughly continuous drum of winding direction (circumferencial direction, sense of rotation); So; In that continuous sheet fiber assembly 1J is wrapped in 1311 last times of coiling frame roughly consistent because of the tension force that winding produces at winding direction (circumferencial direction), can on continuous sheet fiber assembly 1J, not produce scar, cut-out etc. during winding, can access the high core of reliability 5, vacuum insulation material 7.

In this mode of execution; Though coiling frame 1311 has used at winding direction (circumferencial direction) roughly continuously and be circumference parts 1312 roughly cylindraceous; But, also can not the general cylindrical shape shape, also can be polygonal (octagonal shape, hexagon shape, planar etc.).

Figure 10 is the figure of expression mode of execution 1, is the schematic representation of other coiling frame.Among Figure 10, (a) being the figure of an example of the octagonal coiling frame of expression, (b) is the figure that expression is wrapped in continuous sheet fiber assembly 1J the state on the octagonal coiling frame.As shown in the figure, circumference parts 1312 also can not be continuous at winding direction (circumferencial direction).In Figure 10; Coiling frame 1311 with bar-shaped (for example; Corner post, cylinder) circumference parts 1312 the circumferencial direction approximate equality be arranged on eight positions, through with running shaft 1315 being the center rotation, twine continuous sheet fiber assembly 1J from grey cloth reel 1301.Shown in figure 10; For example, at a plurality of (for example, eight positions) circumference parts 1312 not under the continuous situation of winding direction; Because can be with gripping members 1320 (referring to Fig. 8; Not shownly in Figure 10 go out) be inserted in winding direction roughly equally spaced between the corner post shape of configuration, a plurality of circumference parts 1312 such as cylindric (spaces between circumference parts 1312 and the circumference parts 1312), the continuous sheet fiber assembly 1J that is wrapped on the coiling frame 1311 is clamped, so; Do not need gripping members that portion 1313 is set, can access simple structure, the light-duty and frame 1311 of reeling cheaply.

In this mode of execution; Possess the continuous sheet fiber assembly 1J that forms by continuous organic fiber 2 and be wrapped in grey cloth roughly cylindraceous continuously with the grey cloth reel 1301 of the nonwoven fabric of long fibers that obtains on the roller 1302 and setting outside grey cloth reel 1301, and the coiling frame 1311 of the width with regulation of the continuous sheet fiber assembly 1J of the nonwoven fabric of long fibers of winding grey cloth reel 1301.Because through (for example being wrapped in grey cloth with the continuous sheet fiber assembly 1J on the roller 1302; Organic fiber aggregate 1) twines the amount of stipulated number R (half the thickness t/2 of predetermined thickness t that are equivalent to necessity of core 5) to coiling frame 1311; Continuous sheet fiber assembly 1J is by the predetermined thickness t of necessity of lamination core 5; So; There is no need the nonwoven fabric sheet (fiber assembly) that many ground laminations are cut into the size (width, length) of regulation, the manufacturing equipment of the enough cheapnesss of ability is made core 5 with low cost simply.

That is, because core 5 through the continuous sheet fiber assembly 1J that forms by continuous fiber (for example, organic fiber 2) (for example; Organic fiber aggregate 1) reel continuously laterally from the inboard and be formed planar, because the end (bent end 5f) of the length direction roughly in four end faces of oblong-shaped and flat core 5 is shaped continuous sheet material bending (folding), so; Two bent end 5f by Bending Processing (folding processing) are not the ends that end face is cut, and therefore, organic fiber 2 can not expose from bent end 5f; In addition; Because end face can be not mixed and disorderly, so, there is no need to cut end face.In addition, reduce at the position of cutting (position), can access core 5, the vacuum insulation material 7 processed with low cost easily.In addition; Because under the situation that the Rack that grey cloth reel 1301 is cut into necessity uses; Roughly the width direction end face of two end faces of the width direction in four end faces of oblong-shaped and flat core 5 and core 5 is suitable; Two end faces of the width direction of core 5 also are cut into Rack in advance when grey cloth reel 1301, so, there is no need after forming core 5, to cut; The manufacturing line of core 5 is simple, can access core 5, vacuum insulation material 7 cheaply.

In addition because do not exist fiber from the end face of core 5 expose or end face mixed and disorderly, so; There is no need to cut end face, therefore, also do not exist because of the cutting end face; Make the fiber length of remaining fiber shorten, remaining fiber overflows from the end face of cutting, diminishes the situation of encapsulation of the closure of outer packaging material 4.

In addition; Shown in figure 24; Use from the inboard laterally coiling continuously at vacuum insulation material 7,750,760; By lamination is under the situation of flat core 5,550,560, and the cross section of the length direction of the length direction end (bent end 5f) of core 5 (with the rectangular cross section of width direction) is shaped as the general triangular shape.Figure 24 is the figure of expression mode of execution 1; It is the schematic representation of the shape of expression vacuum insulation material; Figure 24 (a) is the analysing and observe of length direction (with the rectangular cross section of the width direction) figure of vacuum insulation material 7,750,750, and Figure 24 (b) is from seeing the major component front view of the length direction end of vacuum insulation material 7,750,760 with the rectangular direction of length direction.

Among Figure 24; Use from the inboard laterally coiling continuously at vacuum insulation material 7,750,760; By lamination is under the situation of flat core 5, by length direction two end part Lf (part of the length L 2) formation of flat partes glabra Lg (part of length L 1) and cross section general triangular shape.At this moment; If the two end part (bent end 5f) of the length direction of core 5 are inserted into outer packaging material 4; Under the state that has been depressurized, be closed; Then the sectional shape of length direction two end part Lf (sectional shape of meet at right angles with width direction (vertical)) just with respect to length direction laterally direction be that diminish the gradually sectional shape (with the rectangular sectional shape of (vertical) of width direction) of such length direction of thickness is a general triangular, outer packaging material 4 is difficult to gauffer more, in addition; Be difficult to break, can access the high vacuum insulation material of reliability.Promptly; Obtain possessing width with regulation; And the fiber assembly in the continuous sheet of length direction is formed the core 5 of flat stromatolithic structure and core 5 is accommodated in inside from opening portion 4a with the state of reeling laterally from the inboard; And under the state that is depressurized with inside; With the outer packaging material 4 of the airbond property of opening portion 4a sealing, under the state that core 5 is depressurized in the packaging material 4 outside, in the length direction end of above-mentioned core 5 (as the bent end 5f at the two end part of length direction) with the rectangular sectional shape of width direction be the such vacuum insulation material of general triangular that thickness diminishes towards the length direction outside gradually.In addition; Carrying out a vacuum insulation material 7,750,760 is bent under the situation of processing such as drum; The end face that makes length direction each other to the end face that fetches under the situation about connect using, make plural a plurality of vacuum insulation material 7,750,760 each other to the situation that fetches use under; If the mode that contacts with each other with the chamfered portion (the inclined plane part Lfs of Figure 24) of the end face of the general triangular shape of a plurality of vacuum insulation materials 7,750,760 connects; Then can reduce the bond thickness of contact segment; And can reduce heat leak from contact segment, can access high performance vacuum insulation material 7,750,760, carry the machines such as refrigerator of vacuum insulation material 7,750,760.

(laminating method of fiber assembly, the production method of core 3)

Then, to a plurality of grey cloth reels 1301 are made up, the method for making core 5 describes.Figure 11 to Figure 14 is the figure of expression mode of execution 1; Figure 11 is that expression is with a plurality of grey cloth reel combinations; The figure of structure with combination grey cloth reel of a big width; Figure 12 is to use two combination grey cloth reels; The schematic representation of the structure of the schematic representation of the wind of the situation of twining to the coiling frame, Figure 13 organic fiber aggregate that to be expression twined by the wind that uses two combination grey cloth reels (upside grey cloth reel, downside grey cloth reel), Figure 14 are the sectional views of the core that twined by the wind that uses two combination grey cloth reels.

For example; Will be by a plurality of grey cloth reels of being twined (for example with roughly the same coiling number of times (identical lamination number); Main part A1301a, main part B1301b, main part C1301c, main part D1301d) with width direction (transverse direction) in abutting connection with (hope is seamlessly to arrange, still, as after need under the situation in gap stating; Also predetermined gap can be set) mode make up, form the first grey cloth reel 1305 (upside reel) with Rack.In addition; With the first grey cloth reel 1305 likewise will be by a plurality of grey cloth reels of being twined (for example with identical coiling number of times (identical lamination number); Main part E1301e, main part F1301f, main part G1301g, main part H1301h are all not shown to be gone out) with at width direction (transverse direction) in abutting connection with (hope is seamlessly to arrange; But, also predetermined gap can be set) mode make up, form the second grey cloth reel 1306 (downside reel) with Rack.

Here, a plurality of grey cloth reels (for example, main part A1301a, main part B1301b, main part C1301c, main part D1301d) can be identical width, also can be different widths.Equally; A plurality of grey cloth reels (for example; Main part E1301e, main part F1301f, main part G1301g, main part H1301h are all not shown to be gone out) can be identical width; Also can be different widths, the quantity of the quantity of a plurality of grey cloth reels that the first grey cloth reel 1305 uses and a plurality of grey cloth reels that the second grey cloth reel 1306 uses can be identical, also can be different.

Because the first grey cloth reel 1305 and the second grey cloth reel 1306 all are to arrange at width direction with the mode of a plurality of grey cloth reels (for example a plurality of main part) adjacency; So there is gap (micro-gap, specified gap) in (for example, main part A1301a, main part B1301b etc.) between the adjacent main part; Adjacent main part (for example; Main part A1301a, main part B1301b etc.) and discontinuous, but interrupted, therefore; There is slit portion (for example, slit portion C between the slit portion B between the slit portion A between main part A1301a and the main part B1301b, main part B1301b and the main part C1301c, main part C1301c and the main part D1301d etc.).In addition; In this mode of execution; At least one of the first grey cloth reel 1305, the second grey cloth reel 1306 uses the distolateral grey cloth reel that is configured in width direction (for example, main part A1301a, main part D1301d, main part E1301e, main part H1301h etc.) in a plurality of grey cloth reels to have ear's grey cloth reel (referring to Figure 11) of the irregular ear of crest line that when grey cloth reel raw material being cut into the width of regulation, produces.

In this mode of execution, (four of main part E1301e, main part F1301f, main part G1301g, main part H1301h) is identical for the quantity of a plurality of grey cloth reels of quantity of a plurality of grey cloth reels that the first grey cloth reel 1305 uses (four of main part A1301a, main part B1301b, main part C1301c, main part D1301d) and 306 uses of the second grey cloth reel.In addition; A plurality of grey cloth reels (main part E1301e, main part F1301f, main part G1301g, main part H1301h) that a plurality of grey cloth reels (main part A1301a, main part B1301b, main part C1301c, main part D1301d) that the first grey cloth reel 1305 uses and the second grey cloth reel 1306 use dispose at the width direction established amount Xb (referring to Figure 14) that staggers respectively; Be wound on the first grey cloth reel 1305 first (organic) fiber assembly 1K be wound on the second grey cloth reel 1306 second (organic) fiber assembly 1H about (with respect to sheet face approximate right angle direction) overlapping; With the staggered state of established amount Xb of the width direction of sheet face, be wrapped in coiling frame 1311 together.For example, having represented that first (organic) fiber assembly 1K can be the organic fiber aggregate, also can be the situation of other fiber assembly (for example, inorfil aggregate).With regard to second (organic) fiber assembly 1H, also be same.At this moment, the first grey cloth reel 1305 and the second grey cloth reel 1306 are configured in fore-and-aft direction or above-below direction, tilted direction with respect to the movement direction of first (organic) fiber assembly 1K, second (organic) fiber assembly 1H (direction of being twined).The width of a plurality of grey cloth reels of the second grey cloth reel 1306 corresponding with a plurality of grey cloth reels of the first grey cloth reel 1305 roughly is equal to, and established amount Xb staggers.

Promptly; Each grey cloth reel that constitutes the first grey cloth reel 1305 (for example; Main part A1301a) and the width of each grey cloth reel (for example, main part E1301e) that constitutes the second grey cloth reel 1306 at the rear be configured in this first grey cloth reel 1305 (perhaps below etc.) roughly be equal to.Equally, each grey cloth reel (main part B1301b and main part F1301f, main part C1301c and main part G1301g, main part D1301d and main part H1301h) is configured to roughly be equal to width respectively.Here, hope that the Rack of the first grey cloth reel 1305 (coiling) and the Rack of the second grey cloth reel 1306 (downside reel) roughly are equal to.

In addition; In this mode of execution; Shown in figure 12; The first grey cloth reel 1305 (upside reel) of core manufacturing installation is that the first grey cloth reel 1305 (coiling) is compared with the second grey cloth reel 1306 (downside reel) with the configuration of the second grey cloth reel 1306 (downside reel), is configured in rear side (perhaps upside, oblique upside etc.) with respect to coiling frame 1311 directions (direction of feed of continuous sheet fiber assembly 1J).That is,, be configured according to the order of the second grey cloth reel 1306 (downside reel), the first grey cloth reel 1305 (upside reel) towards coiling frame 1311 directions.At this moment, being wound onto first (organic) fiber assembly 1K on the first grey cloth reel 1305 (upside reel) compares with second (organic) fiber assembly 1H on being wound onto the second grey cloth reel 1306 (downside reel) and is configured in upside.Owing to twined by coiling frame 1311; So; Be wound onto first (organic) fiber assembly 1K on the first grey cloth reel 1305 (upside reel) with respect to second (organic) fiber assembly 1H that is wound onto on the second grey cloth reel 1306 (downside reel), twined with the mode in the radial direction outside that always is positioned at coiling frame 1311.Here, as long as dispose first grey cloth reel 1305 (upside reel) and the second grey cloth reel 1306 (downside reel) to make first (organic) fiber assembly 1K and second (organic) fiber assembly 1H be wrapped in the structure on the coiling frame 1311 under overlapping up and down state mode.

Here, if under the situation that the Rack of necessity is little in goods (for example, about 100mm or 200mm); The manufacturing of grey cloth reel (the first grey cloth reel 1305 (upside reel), the second grey cloth reel 1306 (downside reel) etc.) does not need the place yet; Easily, still, under the situation that necessary Rack is big in goods (for example; 1100mm or 2000mm etc.), the manufacturing difficulty of grey cloth reel (the first grey cloth reel 1305 (upside reel), the second grey cloth reel 1306 (downside reel) etc.).In addition, though according to goods, existence needs the situation of the different vacuum insulation material of width 7; But,, then need the grey cloth reel of the quantity of necessary Rack if desire is corresponding through a grey cloth reel; The not only manufacturing of grey cloth reel difficulty, and the kind of grey cloth reel increases, and cost improves.Therefore, in this mode of execution, a plurality of grey cloth reels are made up with the mode in the width direction adjacency, use as combination reel (the for example first grey cloth reel 1305, the second grey cloth reel 1306).

If as this mode of execution, (width is different) grey cloth reel (for example, main part A1301a, main part B1301b, main part C1301c, main part D1301d) that makes a plurality of width is in the width direction adjacency; As the grey cloth reel of a big width (for example; The first grey cloth reel 1305) use, then the width of each grey cloth reel is little also passable, therefore; Needn't select the manufacturing site location of grey cloth reel (for example, main part A1301a, main part B1301b etc.) to make easily.And, when the grey cloth reel of the big width of needs, can be with the grey cloth reel combination of a plurality of little width; A grey cloth reel making big width (for example; The first grey cloth reel 1305, second grey cloth reel 1306 etc.), needn't select the manufacturing site location of grey cloth reel, in addition; The kind of grey cloth reel be can reduce, can the big core of design freedom 5, vacuum insulation material 7 be obtained with low cost.For example; Grey cloth reel that also can a plurality of width are different (main part A1301a, main part B1301b etc.) combination; Or the little grey cloth reel that a plurality of width roughly are equal to (for example; Identical grey cloth reels of width such as main part B1301b) combination is as the grey cloth reel of a big width.

In addition; In this mode of execution; Will be (for example by a plurality of grey cloth reels; Main part A1301a, main part B1301b, main part C1301c, main part D1301d) first (organic) the fiber assembly 1K that twined on the first grey cloth reel 1305 (coiling) of the conduct combination grey cloth reel that constitutes and (for example by a plurality of grey cloth reels; Main part E1301e, main part F1301f, main part G1301g, main part H1301h) the second grey cloth reel 1306 (lower mandrel member) of the conduct combination grey cloth reel that constitutes goes up second (organic) fiber assembly 1H that twines and staggers established amount Xb (for example about 5mm～40mm at width direction (transverse direction); Preferred 10mm～20mm) configuration, it the reasons are as follows.

(1) for example, owing in fact the connection part because of the grey cloth reel in the width direction adjacency (for example, main part A1301a and main part B1301b etc.) in a plurality of grey cloth reels (main part A1301a, main part B1301b, main part C1301c, main part D1301d) that constitute the first grey cloth reel 1305 exists some gaps; Even do not join but there is the gap; Also also discontinuous there is slit portion (for example, between main part A and main part B, having slit portion A) in abutting connection with the position, so; Established amount Xb ground lamination is many if do not stagger; Then slit portion (joint, adjacent portion) appears at roughly equivalent site, therefore, at slit portion by disjunction.That is and since because of slit portion (joint, adjacent portion) discontinuous from slit portion fracture or by seized disconnected, so; Can not obtain the necessary flexural strength as core 5, slit portion (adjacent portion) is discontinuous, becomes the crack; Therefore, it is in disorder to become from here on, and outer packaging material 4 breaks etc.; The core 5 of necessary width can not be obtained, in addition, performance can not be obtained as vacuum insulation material 7.In this mode of execution; Because with respect to the first grey cloth reel 1305 (coiling); With the second grey cloth reel 1306 (lower mandrel member) with the ground lamination multilayer that staggers by the superimposed mode of established amount Xb; So, do not exist because of the friction of the part of the established amount Xb that staggers etc. in disorderly or by the situation of disjunction at slit portion (in abutting connection with the position), can access the core 5 of size of the regulation of necessity with necessary heat-shielding performance.

(2) though in abutting connection with the position with the first grey cloth reel 1305 (coiling) and the second grey cloth reel 1306 (lower mandrel member) to stagger by the superimposed mode of established amount Xb; But; Owing to there is slit portion (in abutting connection with the position); So first (organic) fiber assembly 1K, second (organic) fiber assembly 1H distinguish not continuous at grade.Therefore, be prone to bending at the slit portion partial volume.In vacuum insulation material in the past, implement the special way of groove processing etc. for bending, manufacture cost improves; But in this mode of execution; Because in manufacture process, the position of adjacency (slit portion) made to bending easily, so; Can the position of this easy bending be configured in the position that is necessary bending of goods, be used effectively.For example, under the situation that is refrigerator, consider to stride between the wall with the angle of regulation (for example roughly 90 degree) bending such as back face wall and upper wall and dispose vacuum insulation material 7, still; Need big vacuum insulation material 7 for this reason, and need bending, therefore; Because need be used to make the big manufacturing equipment of grey cloth reel raw material, manufacturing site location is defined or makes difficulty, because need be used for the special processing of bending; So cost also improves, corresponding difficulty.In the vacuum insulation material 7 of this mode of execution,, use as a big grey cloth reel because can make a plurality of grey cloth reels in the width direction adjacency; And, as long as be necessary the position configuration slit portion (adjacent portion) of bending, so; Select the width of grey cloth reel the combination free of grey cloth reel that can be through little width, in addition, need not be used for the special processing of bending; In addition, because make up, can make the core 5 of big width through the grey cloth reel of will be a plurality of little width; So, can stride in the past difficulty refrigerator etc. with configuration vacuum insulation material 7 between the wall of the angle bending of regulation.

(3) both side ends of the width direction of the grey cloth reel raw material that the cutting of width direction two ends is preceding is called as ear; Because there is not the amount of necessary thickness in the fiber of organic fiber aggregate 1, continuous sheet fiber assembly 1J and on thickness, produces inconsistent; Or the crest line of width direction end face is irregular, so, when using as the grey cloth reel; Be necessary grey cloth reel raw material is cut both sides with the Rack of necessity in advance, use as the grey cloth reel.Therefore, the ear's grey cloth reel that the ear of the two side portions of width direction has been cut from this grey cloth reel raw material is because weak strength, and end face (crest line) is irregular, goes out of use in the past.In this mode of execution; With such shown in the ear's grey cloth reel that went out of use (in this mode of execution, for example being equivalent to main part A1301a, the main part D1301d) image pattern 11 in the past, be used for constituting the employed grey cloth reel in width direction both sides (for example main part A1301a, main part D1301d etc.) of a plurality of grey cloth reels of the first grey cloth reel 1305, the second grey cloth reel 1306; The established amount Xb lamination multilayer because the first grey cloth reel 1305, the second grey cloth reel 1306 stagger; So the part quilt of ear and non-ear is lamination alternately, because the ear position by configuration with staggering; So, do not exist ear and ear continuously by the situation of lamination.In view of the above, even use ear's grey cloth reel, also obtain core 5 necessary intensity.

Here; Shown in figure 11; The first grey cloth reel 1305 is configured in the mode of width direction adjacency successively with main part A1301a, main part B1301b, main part C1301c, main part D1301d, still, and here; The width of main part A1301a, main part B1301b, main part C1301c, main part D1301d is respectively T1, T2, T3, T4, and the width of the first grey cloth reel 1305 is TA (TA=T1+T2+T3+T4).Therefore, need only the width (T1, T2, T3, T4) that determines each grey cloth reel of the first grey cloth reel 1305 with the necessary Rack of goods with matching.As long as likewise determine the width of each grey cloth reel of the second grey cloth reel 1306.That is, as long as the width (width of main part E1301e, main part F1301f, main part G1301g, main part H1301h) of selected main part A1301a, main part B1301b, main part C1301c, main part D1301d.At this moment, width T1, T2, T3, T4 can be identical, also can be different.

Therefore; Because can individually suitably (for example select a plurality of grey cloth reels; Main part A1301a, main part B1301b, main part C1301c, main part D1301d, main part E1301e, main part F1301f, main part G1301g, main part H1301h) width; So degree of freedom in design increases, and can access machines such as core 5, vacuum insulation material 7 and refrigerator cheaply.In addition, because the first grey cloth reel 1305 and the second grey cloth reel 1306 are wrapped in coiling frame 1311 with staggering established amount Xb, make core 5; So; In the easy bending of slit portion, can not need special processing etc., make easily can bending vacuum insulation material 7; Heat insulation wall to having with the such machines such as refrigerator of the such heat insulation wall of predetermined angular bending also is provided with easily; Therefore, the clad ratio of vacuum insulation material 7 can be enlarged, high-performance, vacuum insulation material, machine cheaply can be accessed.

Shown in figure 13; Be wrapped in 1311 last times of coiling frame at continuous sheet fiber assembly 1J, be wrapped on the coiling frame 1311 with the state of the established amount Xb that staggered from first (organic) fiber assembly 1K (first (organic) fiber assembly 1Ka～1Kd, upside organic fiber aggregate) of the first grey cloth reel 1305 (upside reel) with from second (organic) fiber assembly 1H (second (organic) fiber assembly 1Ha～1hd, downside organic fiber aggregate) of the second grey cloth reel 1306 (downside reel).1H is shown in figure 14 to be wrapped in first (organic) fiber assembly 1K, second (organic) fiber assembly on the cross section vertical with winding direction under the state on the coiling frame 1311; With the state of the established amount Xb that staggered by lamination alternately; Twined continuously laterally from the inboard, and by lamination.Therefore; The established amount Xb because first (organic) fiber assembly 1K and second (organic) fiber assembly 1H stagger; So; The distance of second slit portion 58 (downside slit portion) of first slit portion 57 (upside slit portion) of first (organic) fiber assembly 1K (upside organic fiber aggregate) and second (organic) fiber assembly 1H (downside organic fiber aggregate) is equivalent to offset Xb; First (organic) fiber assembly 1K and second (organic) fiber assembly 1H are overlapping and by lamination with the amount of this Xb, because friction etc., first (organic) fiber assembly 1K is difficult to separate with second (organic) fiber assembly 1H.

Here; Lamination the thickness t under the state (state of decompression) that vacuumized of the core 5 of a plurality of organic fiber aggregates 1 (continuous sheet fiber assembly 1J, first (organic) fiber assembly 1K, second (organic) fiber assembly 1H) is thick more is difficult to bending more; But, in this mode of execution, owing to there are two slit portions (first slit portion 57, second slit portion 58) in the position of leaving established amount Xb; So; Through in the ground bending of two stages of these two slit portions (first slit portion 57, second slit portion 58), though the thickness thickening, also bending easily (the bending angle that obtains stipulating).

In this mode of execution, correspondingly determine superimposed surplus Xb with the thickness of core 5.That is,, can make established amount Xb little at the thickness of core 5 hour, but owing to if the thickness of core 5 is big, then be difficult to bending, so, suitably increase established amount Xb and come corresponding.Here, if established amount Xb is too small, then overlap length (superimposed surplus) shortens; Can not obtain frictional force; First (organic) fiber assembly 1K, second (organic) fiber assembly 1H separate at superimposed (between the main part), can not obtain the core 5 of Rack, therefore; In this mode of execution, superimposed surplus Xb is at (more than the preferred 10mm) more than the 7mm.In superimposed surplus is under the situation of 5mm; Because superimposed surplus is short; So; Can not obtain necessary friction, (first (organic) fiber assembly 1Ka～1Kd, second (organic) fiber assembly 1Ha～1Hd) separate from slit portion can not obtain having the core 5 of the width of regulation to each organic fiber aggregate of first (organic) fiber assembly 1K, second (organic) fiber assembly 1H.Here, known at superimposed surplus Xb under the situation more than the 10mm, even superimposed is used ear, also can stably obtain frictional force, and also the reduction with pyroconductivity suppresses for a short time.

In addition,, can obtain necessary friction by the earth more because superimposed surplus Xb is big more, so; As core 5, reliability improves, and is good, still; If with respect to the thickness of vacuum insulation material 7, superimposed surplus Xb is excessive, then the distance (Xb) between two slit portions becomes big when bending, and it is big that the width of bending part becomes; In addition, be difficult to bending, therefore, under situation with vacuum insulation material 7 bendings; Superimposed surplus Xb the thickness of vacuum insulation material 7 below about three times for well (for example, when the thickness t of vacuum insulation material is 10mm, superimposed surplus Xb below about 30mm for well).

Figure 15 is the figure of expression mode of execution 1, is to use the combination grey cloth reel with three grey cloth reel combinations, is wrapped on the coiling frame stereogram of the core 550 of the situation of manufacturing core 550.Among Figure 15; Core 550 is through the main points same with the core of Figure 11～shown in Figure 14 5; From being wrapped in coiling frame 1311 under first (organic) fiber assembly 1K (first (organic) fiber assembly 1Ka, 1Kb, 1Kd) (upside organic fiber aggregate) of the first grey cloth reel 1305 (upside reel) and second (organic) fiber assembly 1H (second (organic) fiber assembly 1Ha, 1Hb, 1Hd) (downside organic fiber aggregate) state, twine continuously laterally from the inboard and by lamination with the established amount Xb that staggers from the second grey cloth reel 1306 (downside reel).And, by two gripping memberss 1,320 two positions are clamped, by bending, make flat core 550 in clamped part.Here, in Figure 15, except that the symbol shown in this figure, be omitted.The parts that vacuum insulation material 702 (not shown go out) is to use core 550 to make.

Core 550 is made up of two bending part 551f (bent end) of clamped parts 1320 bendings (folding) and the flat plat part 551g (partes glabra) that is set between two bending part 551f.In addition; The adjacent portion of each first (organic) fiber assembly 1Ka of first (organic) fiber assembly 1K (upside organic fiber aggregate), 1Kb, 1Kd is first slit portion 57 (upside slit portion) shown in Figure 14, and the adjacent portion of each second (organic) fiber assembly 1Ha of second (organic) fiber assembly 1H (downside organic fiber aggregate), 1Hb, 1Hd is second slit portion 58 (a downside slit portion).The distance (length) of the width direction of this first slit portion 57 and second slit portion 58 is equivalent to offset Xb.Therefore, can carry out Bending Processing at this first slit portion 57 and second slit portion 58 easily.

Here, the end end 551Je that reels is configured in Figure 15 on the plat part 551g, but hopes to be configured near the bending part 551f.Be configured in plat part 551g because finish end 551Je if reel, it is poor then to produce ladder at plat part 551g easily, so bad.In addition, because when through gripping members 1320 core 551 being formed planar, the end end 551Je that reels leaves from the position of gripping members 1320, so, elongated in the position and the length between the coiling end end 551Je of this gripping members 1320.Because in the position of this gripping members 1320 and the part that finishes first (organic) fiber assembly 1K, second (organic) fiber assembly 1H between the 551Je of end of reeling not clamped; So; Existence is from the at random and possibility of bending of core 550; So the end end 551Je that should reel be cut near the bending part 551f that can be clamped by gripping members 1320.Preferably (preferably just having clamped the back) cuts after being clamped by gripping members 1320, preferably near bending part 551f, do not cut in the scope of plat part 551g generation ladder difference.The possibility of in disorder and bending reduces, and it is poor to be difficult to produce ladder at plat part 551g, and the ladder difference can not be blocked, and in addition, appearance might as well.

Figure 16 is the figure of expression mode of execution 1, is to be used for figure that other the structure of combination grey cloth reel is described.Here; Shown in figure 16; The first grey cloth reel 1305, the second grey cloth reel 1306 at the conduct that is made up of a plurality of grey cloth reels combination grey cloth reel use under the situation of three grey cloth reels (main part A1301a, main part B1301b, main part D1301d), and the grey cloth reel of width direction both sides (main part A11301a, main part D1301d1) also can use one-sided ear's grey cloth reel as ear.In this case, also can be configured in the body blank cloth reel as the grey cloth reel that does not have ear of central authorities with the ear towards ear's grey cloth reel, just the mode of main part B11301b side is arranged.

Among Figure 16; The first grey cloth reel 1305 (upside reel) as combination grey cloth reel is made up of main part A1301a, main part B1301b, main part D1301d, arranges at width direction with the mode according to the order adjacency of main part A1301a, main part B1301b, main part D1301d.Promptly; The main part B1301b that does not have ear in the configuration of width direction middle position as body blank cloth reel; Configuration has the main part A1301a as ear's grey cloth reel, the main part D1301d of ear in its both sides, is configured with the ear's side and the mode that is configured in the main part B1301b side adjacency that does not have ear of middle position of ear's grey cloth reel.Though not shownly go out, also be and the same structure of the first grey cloth reel 1305 (upside reel) as the second grey cloth reel 1306 (downside reel) of combination grey cloth reel.Promptly; Not have the main part F1301f as body blank cloth reel of ear in the configuration of width direction middle position; Dispose the main part E1301e as ear's grey cloth reel, the main part H1301h with ear in its both sides, ear's side of ear's grey cloth reel is configured with the mode that is configured in the main part main part F1301f side adjacency that does not have ear of middle position.Though not shownly go out, with the parts that are shaped by the grey cloth reel of Figure 16 also as core 550, the parts that vacuum insulation material 702 is to use core 550 to make.

Like this, be not configured in as the first grey cloth reel 1305 of combination reel, the width direction both end sides of the second grey cloth reel 1306 because be wound on the ear of the ear's organic fiber aggregate on ear's grey cloth reel, so; Twining, during shaping core 550, not ear in the width direction both sides to coiling frame 1311; But generation cutting surface; Therefore, there is no need both sides cutting, can access vacuum insulation material 702 cheaply the width direction of core 550.At this moment; Body blank cloth reel (main part B1301b) will not having ear is configured in the width direction middle position; Have in the configuration of its both sides under the situation of ear's grey cloth reel (main part A1301a, main part D1301d) of ear, also can dispose with the mode of body blank cloth reel (main part B1301b) the side adjacency of any ear in the ear of ear's grey cloth reel (main part A1301a, main part D1301d) and middle position.Also can be only to dispose ear's grey cloth reel in the one-sided mode that produces ear that makes up the grey cloth reel; In this case; Compare with the situation of configuration ear grey cloth reel in the both sides of combination grey cloth reel; As long as only, therefore, can access vacuum insulation material 702 cheaply with a side width direction side cutting.Certainly; Even have ear's grey cloth reel (main part A1301a, main part D1301d) of ear; If only there is the amount of necessary thickness in the fiber of ear, the inconsistent little or endface position (crest line) of thickness inconsistent little, no problem level in the heat-shielding performance of core 550, vacuum insulation material 702, manufacturing; Even it is distolateral then ear's grey cloth reel to be used to make up the width direction of grey cloth reel, also there is no need the width direction end face is cut.

Therefore; In this mode of execution; With regard to the manufacturing of core 550; There is no need many ground laminations; The simple equipment that can be enough only fiber assembly 1J be twined can be made, so, (for example constitute as first (organic) fiber assembly 1K of conjugate fiber aggregate 1J; First (organic) fiber assembly 1Ka～1Kd) perhaps (for example constitute second (organic) fiber assembly 1H; A plurality of fiber assemblies of second (organic) fiber assembly 1Ha～1Hd) (for example, at least one of first (organic) fiber assembly 1Ka～1Kd, second (organic) fiber assembly 1Ha～1Hd) can use easily went out of use in the past at the distolateral ear's fiber assembly (for example, being wound onto the main part A1301a as ear's grey cloth reel, the fiber assembly on the main part D1301da) of width direction with crest line irregular (not being cutting surface) ear.In view of the above, the ear's fiber assembly with ear that will in the past not go out of use (being wound onto the fiber assembly on ear's grey cloth reel) cutting etc. can former state utilize ear's grey cloth reel, can not produce waste.Therefore, can access core 550, vacuum insulation material 702 cheaply.

Figure 17 is the figure of expression mode of execution 1, be expression with vacuum insulation material 750 bendings the stereogram of appearance.Among Figure 17, Figure 17 (a) be with vacuum insulation material 750 bendings the stereogram of state, Figure 17 (b) is the main position enlarged view of the bending part of vacuum insulation material 750.Vacuum insulation material 750 is closed under the state that inside is depressurized in core 550 is inserted into the outer packaging material 4 with airbond property.Vacuum insulation material 750 by the bending of two stages, forms bending part 59 in the part of first slit portion 57 of core 550, second slit portion 58.At this moment, the width of bending part 59 is by the width bending of superimposed surplus Xb.The width of superimposed surplus Xb is equivalent to the distance (length) of first slit portion 57 and second slit portion 58, is identical length roughly.

In addition; Because vacuum insulation material 750 be with organic fiber aggregate 1, continuous sheet fiber assembly 1J width direction stagger superimposed surplus Xb overlapping two and lamination have a plurality of, so, through staggering superimposed surplus Xb; Outside first slit portion 57, second slit portion 58 are inserted in the packaging material 4; When having carried out decompression, packaging material 4 in first slit portion 57, second slit portion, 58 depressions, forms depressed part 751,752 respectively.In addition, the part with these two first slit portions 57, second slit portion 58 forms the roughly protuberance 753 of trapezoidal shape to two depressed parts 751 of depression, mode outstanding between 752 respectively.Because the depressed part 751,752 that bending part 59 is caved in respectively by the part of two first slit portions 57, second slit portion 58 and constitute with protuberance 753 to two depressed parts 751, outstanding mode forms between 752 roughly trapezoidal shape; So; Through being basic point with this depressed part 751,752; Utilize the roughly inclined-plane of the protuberance 753 of trapezoidal shape, bending easily.In addition, because the depressed part 751,752 of the part of first slit portion 57, second slit portion 58 and the protuberance 753 that is formed on these depressed parts 751, the trapezoidal shape between 752 produce in the both sides of the thickness direction of vacuum insulation material 750, so; Even for example under the situation of the thickness thickening of vacuum insulation material 750, also can be in first slit portion 57 of the both sides that are formed on the sheet face, the part bending easily of second slit portion 58, therefore; Even bending; Do not exist outer packaging material 4 to break yet or damage, the situation that heat-shielding performance reduces, therefore; Reliability is high; Can suppress the reduction of heat-shielding performance, can access the influence that does not receive thickness, that can carry out bending is provided with the high vacuum insulation material of degrees of freedom.

To as this mode of execution; In the vacuum insulation material 750 that possesses by the bending part 59 that constitutes through a plurality of first slit portions 57, depressed part 751,752 that second slit portion 58 forms and the protuberance 753 that is formed on the roughly trapezoidal shape of this first slit portion 57, second slit portion 58; With the thickness t is 5mm, 7mm, 10mm, 30mm; Carried out the bending affirmation, all no problem.But, if the thickness t thickening (under the situation of for example t=30mm) of vacuum insulation material 7, then like Figure 12, shown in Figure 13; Because if the overlapping number of organic fiber aggregate 1, continuous sheet fiber assembly 1J (first (organic) fiber assembly 1K, second (organic) fiber assembly 1H) is two (among Figure 12; Two of first (organic) fiber assembly 1K, second (organic) fiber assembly 1H), then with respect to the bending part 59 at a position, slit portion is two positions; So; Depressed part 751,752 is also few to two positions, and is inconvenient crooked, therefore; Still make overlapping number more than three; Make with respect to the slit portion of the bending part 59 at a position at three more than the position, be the depressed part that produces by slit three more than the position for well, the material of the material of the thickness t of vacuum insulation material 750, organic fiber aggregate 1, characteristic, outer packaging material 4, pull intensity etc. as long as suitably select.

As stated, if as this mode of execution, owing to organic fiber aggregate 1, continuous overlapping many of sheet fiber assembly 1J (for example two); At the width direction repeatedly lamination of specific length (superimposed surplus Xb) that staggers; Make core 5,550, then can make with respect to the quantity of the slit of the bending part at a position for the quantity of the number that organic fiber aggregate 1, continuous sheet fiber assembly 1J is overlapping (under overlapping a plurality of for example situation that three are staggered, with respect to the bending part at a position; Slit is 3); So, even the thickness thickening of vacuum insulation material 750, through (for example by the slit portion of the two sides side that is arranged on the sheet face; First slit portion 57, second slit portion 58) depressed part 751,752 that forms, can make bending part 59 more easily to the bending of the both sides of sheet face.

Here, big, then shown in figure 18 if superimposed surplus Xb becomes, produce the part of the thin thickness of identical length amount roughly with superimposed surplus Xb at the two end part of the width direction of vacuum insulation material 750.Figure 18 is the figure of expression mode of execution 1, is the figure that sees vacuum insulation material 750 from width direction.Vacuum insulation material 750 comprise the thickness t with regulation the 750c of predetermined thickness portion, have regulation thickness t about 1/2 thickness and be set at thinner wall section 750a, the 750b of the width direction both sides of the 750c of predetermined thickness portion.Because this thinner wall section 750a, 750b compare insulating thickness with the 750c of predetermined thickness portion thin, so, to compare with the 750c of predetermined thickness portion, heat-shielding performance reduces slightly.Therefore, because big if superimposed surplus Xb becomes, then the width H1 of thinner wall section 750a, 750b, H2 (with the length of superimposed surplus Xb identical length roughly) become big, so, should superimposed surplus not greatly.That is, superimposed surplus Xb under the situation that vacuum insulation material 750 bendings are used, more than the preferred 7mm, about 30mm below.

In addition, under the situation of not bending ground use, because superimposed surplus Xb is big more, frictional force is big more; Reliability improves, so, superimposed surplus Xb at 7mm with first-class; Preferred 10mm is above for well, because superimposed surplus Xb is big more, the length of thinner wall section 750a, 750b is big more; It is big that part that heat-shielding performance reduces slightly becomes, so preferred superimposed surplus Xb is below about 30mm.In addition because superimposed surplus Xb is influenced by the thickness t of vacuum insulation material 750 also, so, at more than a times of predetermined thickness t of vacuum insulation material 750, below five times about (preferred below three times) for well.In this mode of execution; Make established amount Xb more than 7mm, it is in disorder to suppress core 550, and making established amount Xb is below about three times of thickness t of the core 550 of substantial vacuum states in the packaging material 4 outside; Bending property is good; And, reduce the width at the width direction two end part of core 550, suppress the reduction of heat-shielding performance.In addition; If according to the thickness of the core 550 in when decompression, set the scope of superimposed surplus Xb, then can access reliability (core 550 can not separate or at random at slit portion); In addition, can access easy bending, core 550, vacuum insulation material 750 that heat-shielding performance is good.

In this mode of execution, represented example, still in the ground bending of two stages of two slit portions (first slit portion 57, second slit portion 58); If do not use two combination grey cloth reels that a plurality of grey cloth reels have been made up, and be to use a plurality of, a plurality of combination grey cloth reels are overlapping and be wrapped on the coiling frame with the state of the established amount Xb that staggered; Then because there are a plurality of slit portions, so, can be in the multistage bending; Because can reduce a bending angle on the slit portion; So, can when bending, not apply inappropriate power, and bending is the angle of regulation easily to core 550, outer packaging material 4.In addition since with respect to the bending part 59 at a position in a plurality of stage bendings, so, can also be bent into acute angle, can use as the heat insulation material of all machines.Therefore, can also carry out heat insulation to the pipe arrangements such as condensation tube of machines such as refrigerator, air conditioner.In addition; The vacuum insulation material of this mode of execution is because excellent in bending workability; So, even with pipe arrangements such as condensation tube sandwich carry out between vacuum insulation material and the vacuum insulation material heat insulation, also can be along piping shape bending deflection; Can suppress between vacuum insulation material with the heat leak in gap of pipe, can also suppress the reduction of heat-shielding performance.

Promptly; The vacuum insulation material 7,702,750 of this mode of execution possess with a plurality of organic fiber aggregates 1, continuous sheet fiber assembly 1J in the continuous sheet of length direction first (organic) fiber assembly 1K that width direction is arranged in abutting connection with ground, with respect to first (organic) fiber assembly 1K with up and down or before and after or the overlapping mode in the left and right sides be set up; And second (organic) fiber assembly 1H that a plurality of organic fiber aggregates 1 in the continuous sheet of length direction, continuous sheet fiber assembly 1J are arranged in abutting connection with ground at width direction, reel continuously laterally from the inboard with the state of the established amount Xb that staggered at width direction by first (organic) fiber assembly 1K and second (organic) fiber assembly 1H; And the core 5,550 that the stromatolithic structure that is formed flat continuous sheet fiber assembly 1J constitutes, have core 5,550 is accommodated in inside; The outer packaging material 4 of the airbond property of the closure that is closed around under the state that is depressurized in inside; Because become the substantial vacuum state through the inside that makes outer packaging material 4; Closure is sealed; Externally packaging material 4 seals; So,, can form the core 5,550 of big width through continuous sheet fiber assembly 1J (being wound on the fiber assembly of the main part of grey cloth reel) combination with a plurality of little width.In addition; Because the width of the quantity through suitable selected a plurality of organic fiber aggregate 1, continuous sheet fiber assembly 1J, a plurality of organic fiber aggregate 1, continuous sheet fiber assembly 1J; Can not receive the influence ground of the width of continuous sheet fiber assembly 1J freely to set the width of core 5,550; So the degree of freedom in design of core 5,550, vacuum insulation material 7,702,750 increases.In addition; Because there is no need in order continuous sheet fiber assembly 1J lamination multilayer specially to be cut into each the size of regulation; Many Di carry out lamination; So, need not cut off equipment, laminating apparatus etc., the manufacturing of core 5,550 can be made core 5,550 in the short time by enough simple devices that only continuous sheet fiber assembly 1J is twined easily.

In addition; Can be with can be at the width (width of the main part of grey cloth reel) of the suitably selected organic fiber aggregate 1 of the mode of the position configuration slit portion (adjacent portion) that is necessary bending, continuous sheet fiber assembly 1J; In addition; Can suitably select the superimposed surplus (established amount Xb) of first (organic) fiber assembly 1K and second (organic) fiber assembly 1H, need not be used for the special processing of bending.In addition, because bending part 59 is formed on two sides in the table with respect to the sheet face, so, can utilize first slit portion 57, second slit portion 58 with respect to the two directions bending easily in table of sheet face.

In addition; Because can be in the joint bending between the fiber assembly 1J (main part A1301a, main part B1301b, main part C1301c, main part D1301d) of the adjacency of first (organic) fiber assembly 1K or second (organic) fiber assembly 1H; So; There is no need to be used for separately the processing of the recess etc. of bending, first slit portion 57 that can in because of the process of making core 550, form, depressed part 751,752 bendings easily that second slit portion 58 produces.In addition, owing to the depressed part 751,752 that forms because of first slit portion 57, second slit portion 58 is created in the both sides (in the table of sheet face) of the thickness direction of vacuum insulation material 750, so; Even for example at the thickness thickening of core 550 situation under; Also side forms first slit portion 57, second slit portion 58 on the two sides of sheet face, therefore, compares with the situation that is formed on the single face side; Bending easily; Therefore, the situation that core 550, outer packaging material 4 break or damage when also not existing in bending can suppress heat-shielding performance and reduce.

In addition, because if to make established amount (superimposed surplus) Xb be more than 7mm, and be below three times of thickness t of the core 5 of substantial vacuum states in the packaging material 4 outside; Then since superimposed surplus Xb more than 7mm; So it is in disorder to suppress core 5, and; Can also suppress to become in disorder, heat-shielding performance reduces.In addition, be below three times of thickness t of the core 5 of substantial vacuum states in the packaging material 4 outside because make superimposed surplus Xb, so, can make the bending property of bending part 59 also good.Therefore, can have with the heat insulation material of the machine of two continuous walls of the angle of regulation as refrigerator etc. and use easily, and can suppress the reduction of heat-shielding performance.

In addition; At a plurality of fiber assembly 1J that constitute first (organic) fiber assembly 1K or second (organic) fiber assembly 1H (for example; At least one of first (organic) fiber assembly 1Ka～1Kd, second (organic) fiber assembly 1Ha～1Hd) used under the situation of ear's fiber assembly of the distolateral ear with crest line irregular (not being cutting surface) of width direction; Can use the ear's fiber assembly with ear (being wound on the fiber assembly of ear's grey cloth reel) that in the past went out of use, the waste that can not produce raw material.Therefore, can access core 5,550, vacuum insulation material 7,702,750 cheaply.

In addition; Because the refrigerator, machine of having used the vacuum insulation material of this mode of execution with the joint (slit portion) of vacuum insulation material between the fiber assembly of the adjacency of first (organic) fiber assembly 1K or second (organic) fiber assembly 1H with predetermined angular (for example roughly 90 degree) bending, be configured in have top, bi-side, at least two continuous walls of the heat insulating box of the back side, bottom surface, so; In the past owing to be difficult to vacuum insulation material freely is bent into necessary predetermined angular; So, be difficult to be applied in two continuous walls, still; Because if use the vacuum insulation material 750 of this mode of execution; Then easily in the bending of the position of necessity, so, can be applied in two continuous walls of angle with regulation.Therefore; Because the bight between two of the angle with regulation continuous walls also can dispose vacuum insulation material continuously; So, can significantly improve the clad ratio of external surface area with respect to the casing (outer container) except that door of machines such as refrigerator of vacuum insulation material.For example, if under the situation of refrigerator, can make in the past difficulty with respect to the clad ratio of outer container surface area more than 80%.

(production method 4 of core)

Above, to the fiber assembly 1 of sheet being cut into the size of regulation, many of laminations form core 5; Make vacuum insulation material 7, perhaps behind fiber assembly 1 lamination, end face 5a is cut a plurality of sheet; Form the size of regulation, form core 5, make the situation (production method 1 of core) of vacuum insulation material 7, (for example continuous sheet fiber assembly 1J; The organic fiber aggregate) is wound in coiled type continuously; Make core 5 method (production method 2 of core), a plurality of grey cloth reels are made up at width direction, with a plurality of combination grey cloth reels (for example, combination grey cloth reel 1305,1306) combinations with a big width; Under with respect to the overlapping state of sheet face approximate right angle direction, to twine, the method (autofrettage 3 of core) of making core 5,550 is illustrated.

In the production method 3 of above-mentioned core; To at least respectively using one to arrange a plurality of at width direction a plurality of grey cloth reels; Conduct with a Rack is made up the first grey cloth reel (upside grey cloth reel) 1305 of grey cloth reel and is arranged a plurality of at width direction a plurality of grey cloth reels; The second grey cloth reel (downside grey cloth reel) 1306 with conduct combination grey cloth reel of a Rack; The fiber assembly 1H of the fiber assembly 1K of the first grey cloth reel 1305 and the second grey cloth reel 1306 overlapping with respect to sheet face approximate right angle direction (radial direction of coiling frame 1311) and be wrapped on the coiling frame 1311, made core 5 methods and is illustrated.Here, the situation to the 3rd grey cloth reel 1307 that substitutes the second grey cloth reel 1306 as combination grey cloth reel, use the single grey cloth reel of conduct with first Rack describes.

Promptly; Use Figure 20～Figure 23 at least one grey cloth reel (for example to make with the fiber assembly 1 of continuous sheet, 1J with Rack; The organic fiber aggregate) be wound in continuously coiled type the 3rd grey cloth reel 1307 with first Rack fiber assembly 1,1J and have the width littler than first Rack continuous sheet fiber assembly the fiber assembly 1K of the first grey cloth reel 1305 of a plurality of conducts combination grey cloth reels that become first Rack of width direction combination with the overlapping state of sheet face approximate right angle direction under; The first grey cloth reel 1305 twines with respect to the mode that the 3rd grey cloth reel 1307 becomes the radial direction outside of coiling frame 1311, and the method for making core 560 describes.

Figure 20 be to use at least one grey cloth reel 1307 with first Rack and with width than the little grey cloth reel of first Rack with the mode that roughly is equal to first Rack at least one combination grey cloth reel 1305 in the width direction combination; Being wrapped in the schematic representation of the wind under the situation on the coiling frame 1311, is other the figure of autofrettage of core of this mode of execution of expression.Figure 21 is to use at least one grey cloth reel with Rack 1307 and at least one combination grey cloth reel to be wrapped in the stereogram of the core of making on the coiling frame.Figure 22 has been to use and has used at least one grey cloth reel with Rack and at least one combination grey cloth reel to be wrapped in the sectional view of the core of making on the coiling frame, and Figure 23 has been to use and has used at least one grey cloth reel with Rack and at least one combination grey cloth reel to be wrapped in the stereogram of the vacuum insulation material of the core of making on the coiling frame.

To at least one the grey cloth reel in a plurality of grey cloth reels; (for example make the fiber assembly 1 with first Rack, 1J in the continuous sheet of length direction; The organic fiber aggregate) be wound in continuously coiled type the 3rd grey cloth reel 1307 with first Rack and with have second Rack littler than first Rack at least one a plurality of of the continuous fiber assembly of length direction and first Rack (for example as combination grey cloth reel for the mode that roughly is equal to width makes up; Only be as the grey cloth reel of the combination of the grey cloth reel of second Rack of the width littler or second Rack than first Rack and than second Rack combination of the grey cloth reel of the 3rd Rack of little width perhaps with the combination of ear grey cloth reel etc.) the first grey cloth reel 1305 with the sheet face approximate right angle direction of fiber assembly 1,1J, 1K; The inboard overlapping state of mode of radial direction that the fiber assembly 1 of the 3rd grey cloth reel 1307,1J become coiling frame 1311 twines down, and the situation of making core 560 describes.

Among the figure; The first grey cloth reel 1301 be equal at the first grey cloth reel 1305 illustrated in fig. 12 (the perhaps second grey cloth reel 1306); To being equal to the identical symbol of part mark; Detailed, still, with a plurality of grey cloth reels of roughly cylindric (the perhaps coiled type) that will have been twined roughly the same coiling number of times (identical lamination number) (for example; Main part A1301a, main part B1301b, main part C1301c, main part D1301d) leaving the gap at width direction (can be with the mode that becomes micro-gap in abutting connection with arrangement; Can not have the gap yet and arrange, can also arrange through pad with the mode that specified gap is set) mode make up, be formed with mode with the width that roughly is equal to first Rack.

The 3rd grey cloth reel 1307 be equal at Fig. 6～grey cloth reel 1301 roughly cylindraceous of having reeled illustrated in fig. 9 with Rack at the continuous fiber assembly 1 of length direction, 1J with Rack; To being equal to the identical symbol of part mark, detailed.The 3rd grey cloth reel 1307 has first Rack, with at the continuous fiber assembly 1 of length direction, 1J coiled type ground continuous reeling and the mode with first Rack be formed.Here, the fiber assembly 1, the 1J that are wound on the 3rd grey cloth reel 1307 are continuous at width direction, are configured to the size that the width H with core 560 is equal to.Here; The 3rd grey cloth reel 1307 can be reeled fiber assembly 1, the 1J of first Rack and made; Perhaps through be wound at the fiber assembly that width is bigger than first Rack roughly cylindric after, the mode that becomes first Rack with width dimensions is made width direction cutting.

Here, the grey cloth reel of a plurality of roughly cylindric (the perhaps coiled type) of the first grey cloth reel 1305 (for example, main part A1301a, main part B1301b, main part C1301c, main part D1301d) can be identical width, also can be different widths.In addition, also can be ear's grey cloth reel of that kind shown in Figure 12.

Because the first grey cloth reel 1305 is shown in figure 12, with the first grey cloth reel 1301 are equivalent constructions, (for example be with a plurality of grey cloth reels; A plurality of main parts) the combination grey cloth reel arranged at width direction of the mode of adjacency, so, between adjacent main part (for example; Between main part A (1301a) and the main part B (1301b)) there are micro-gap or a specified gap; Because adjacent body portion is discontinuous, but interrupted, so; There is slit portion (for example, slit portion C between the slit portion B between the slit portion A between main part A1301a and the main part B1301b, main part B1301b and the main part C1301c, main part C1301c and the main part D1301d etc.).In addition; The 3rd grey cloth reel 1307 also can use the distolateral grey cloth reel that is configured in width direction (for example, main part A1301a, main part D1301d etc.) in a plurality of grey cloth reels to have ear's grey cloth reel of the irregular ear of crest line that when grey cloth reel raw material being cut into the width of regulation, produces.

Therefore; Possessing to have reeled has first Rack and at the single grey cloth reel of at least one of the fiber assembly of the continuous sheet of length direction and the width that first Rack roughly is equal to (for example; The 3rd grey cloth reel 1307) and will have than the little width of first Rack and arrange a plurality of at width direction at the fiber assembly of the continuous sheet of length direction; Mode to become the width that roughly is equal to first Rack (has for example made up at least one a plurality of combination grey cloth reels at width direction; The first grey cloth reel 1305); Become with fiber assembly 1,1J under the overlapping state of the inboard mode of the radial direction of coiling frame 1311 at the fiber assembly 1K of fiber assembly 1,1J and the combination grey cloth reel 1305 of the single grey cloth reel 1307 that will have first Rack at the grey cloth reel 1307 single with respect to sheet face approximate right angle direction; From inside to outside be wound in coiled type continuously, form core 560.

Therefore; Only pass through continuous fiber assembly 1,1J, 1K in and winding overlapping with sheet face approximate right angle direction; Can make core 560 easily; In addition, the ear's grey cloth reel that in the past went out of use can be effectively utilized, core 560, the vacuum insulation material 760 of waste can be obtained can not producing with low cost.

Because possess: will have first Rack and at the 3rd fiber assembly (being wound on fiber assembly 1,1J on the 3rd grey cloth reel 1307) of the continuous sheet of length direction with have the width littler than first Rack, and the fiber assembly of the continuous sheet of length direction with the mode that becomes the width that roughly is equal to first Rack width direction across specified gap be arranged with the first a plurality of fiber assembly (as the fiber assembly 1K of the first grey cloth reel 1305 of combination grey cloth reel),

First fiber assembly and the 3rd fiber assembly are with the overlapping state of sheet face approximate right angle direction with respect to the first fiber assembly 1K or the 3rd fiber assembly 1,1J; Be wound into coiled type laterally continuously from the inboard, be shaped as flat fiber assembly the core that constitutes by stromatolithic structure,

Core is accommodated in inside, the outer packaging material of the airbond property of the closure that is closed around having under the state that has been depressurized in inside,

Through the inside of packaging material outside is under the substantial vacuum state closure to be sealed; And outer packaging material sealed the vacuum insulation material of making; So; The end materials such as remaining ear grey cloth reel that the grey cloth reel are cut into Rack can be effectively utilized, therefore, the end materials such as ear that flexible utilization effectively went out of use in the past can be carried out.

In addition; Between as each grey cloth reel of the first grey cloth reel 1305 of combination grey cloth reel (for example; Between main part A and the main part B, between main part B and the main part C, between main part C and the main part D etc.) pad of Rack etc. is set; (for example, between fiber assembly 1Ka and the 1Kb, between 1Kb and the 1Kc, between 1Kc and the 1Kd etc.) set the specified gap of the width of pad between each fiber assembly of the fiber assembly 1K of the first grey cloth reel 1305, therefore; On vacuum insulation material 560, also form the roughly recess of Rack; Can bury pipe arrangement underground or position at this recess, can reduce heat insulation, activity duration that pipe arrangement is provided with of pipe arrangement, can obtain vacuum insulation material, machine cheaply efficiently.

Here; Shown in figure 20; Will be as the 3rd fiber assembly 1 of first (organic) fiber assembly 1K (first (organic) fiber assembly 1Ka, 1Kb, 1Kc, 1Kd) and the 3rd grey cloth reel 1307 of the first grey cloth reel 1305 of combination reel, 1J overlapping with respect to sheet face approximate right angle direction and be wrapped under the situation on the coiling frame 1311, should first (organic) fiber assembly 1K (first (organic) fiber assembly 1Ka, 1Kb, 1Kc, 1Kd) of the first grey cloth reel 1305 is overlapping with the mode of comparing running shaft 1315 with respect to coiling frame 1311 with fiber assembly 1, the 1J of the 3rd grey cloth reel 1307 and becoming outside the radial direction.

Shown in Fig. 9 (e); First (organic) fiber assembly 1K (first (organic) fiber assembly 1Ka, 1Kb, 1Kc, 1Kd) with the 3rd fiber assembly 1 of continuous sheet, 1J and continuous sheet overlaps under the state on the coiling frame 1311; Tension force general cylindrical shape shape with regulation is wrapped on the coiling frame 1311 (coiled type); And will be roughly cylindraceous after fiber assembly 1,1J, 1K clamp by gripping members 1320; Tension force is relaxed; Under the situation that coiling frame 1311 is extracted; Preferably in mode overlapping with respect to sheet face approximate right angle direction and that twine; So that will make up at width direction in abutting connection with ground through making a plurality of fiber assemblies at the 4th fiber assembly with first Rack of width direction free from flaw etc., and compare with first fiber assembly that has crack, gap etc. at width direction be arranged in fiber assembly cylindraceous roughly in all sides so that the 3rd fiber assembly is compared the radial direction that is positioned at coiling frame 1311 with first fiber assembly inboard; Thereby will be roughly under the situation that fiber assembly cylindraceous is extracted from coiling frame 1311, fiber assembly can be in not all sides at random, in disorder or can not be stuck in the coiling frame.

That is,, becoming with respect to first fiber assembly with the 3rd fiber assembly under the overlapping state of inboard mode because under the situation that first fiber assembly and the 3rd fiber assembly are reeled with overlapping state; Be wound on laterally on the coiling frame 1311 from the inboard, so, will be wound on fiber assembly roughly cylindraceous on the coiling frame 1311 when coiling frame 1311 is extracted; Have first Rack, and be configured in the most inboard of fiber assembly cylindraceous roughly, therefore at width direction continuous the 3rd fiber assembly 1,1J; Because it is continuous at width direction to be configured in the most inboard fiber assembly; So, being configured in the most inboard situation with first fiber assembly that will make up and comparing at the fiber assembly of the little width of ratio first Rack of a plurality of arrangements of width direction, fiber assembly can be not at random, in disorder; Perhaps in disorder fiber assembly is stuck in coiling frame 1311 etc. extracting Shi Buhui from coiling frame 1311; Therefore, extract core 560 easy to manufacture easily; Can improve operation property, shorten manufacturing time.In addition, the fiber assembly roughly cylindraceous 1,1J, the 1K that extract from coiling frame 1311 are shaped as planar, the stay in grade of the core 560 of manufacturing.

Here; With regard to the width of the first grey cloth reel, 1305 employed a plurality of grey cloth reels, the quantity number of use (four of main part A1301a, main part B1301b, main part C1301c, main part D1301d); As long as suitably set with the mode that first Rack of fiber assembly 1,1J with the 3rd grey cloth reel 1307 of first Rack roughly is equal to; But; Arrange the width (having added the total width in the gap between a plurality of grey cloth reels and the grey cloth reel) of the first grey cloth reel 1305 when a plurality of at width direction; Be configured to the mode of the width smaller than first Rack of the 3rd grey cloth reel 1305; Will be wound on the first grey cloth reel 1305 fiber assembly 1K be wound on the 3rd grey cloth reel 1307 on fiber assembly 1,1J with the fiber assembly 1K of the first grey cloth reel compare with fiber assembly 1, the 1J of the 3rd grey cloth reel become overlapping and be wrapped in the mode on the coiling frame 1311 with respect to the mode in the sheet face approximate right angle direction outside; Even make that each fiber assembly is difficult in disorder under the situation of twining to coiling frame 1311, twine easily.

In addition; The first grey cloth reel 1305 is compared under the situation about being wrapped on the coiling frame 1311 with fiber assembly 1, the 1J of the 3rd grey cloth reel 1307 with the fiber assembly 1K of the 3rd grey cloth reel 1307 at the first grey cloth reel 1305; Overlapping and twined to become with respect to the mode in the sheet face approximate right angle direction outside, but the production method of vacuum insulation material 560 and Fig. 9 are equal to.Even be wrapped in a grey cloth reel 1301 on the coiling frame 1311 in the alternate figures 9; Be by at least two overlapping grey cloth reels (for example with respect to sheet face approximate right angle direction; Under the situation that the first grey cloth reel 1305 of Figure 12～shown in Figure 180 and the second grey cloth reel 1306 is overlapping, situation that the first grey cloth reel 1305 of Figure 20～shown in Figure 23 and the 3rd grey cloth reel 1307 is overlapping is inferior) combination, the production method of winding method, core, the production method of vacuum insulation material etc. also is equal to operation shown in Figure 9.

As stated; Because possessing has reeled have first Rack and at least one of the continuous fiber assembly of length direction at the single grey cloth reel of width direction (for example the 3rd grey cloth reel 1307) with will reel and have than the little width of first Rack and arrange a plurality of at width direction at the grey cloth reel of the continuous fiber assembly of length direction; Mode to become the width that roughly is equal to first Rack makes up grey cloth reel (the for example first grey cloth reel 1305) in a plurality of at least one of width direction combination; The first grey cloth reel as combination grey cloth reel can use end materials such as ear's grey cloth reel; So; The end materials that there is no need in the past to discard etc. are discarded, can make core, vacuum insulation material effectively with low cost.

In addition because with the fiber assembly 1K of fiber assembly 1,1J and the combination grey cloth reel 1305 of single grey cloth reel 1307 with respect to overlapping many of sheet face approximate right angle direction, from inside to outside twine to coiling frame 1311 cylindraceous roughly with the tension force of regulation; After this, with after roughly fiber collection body and function gripping members 1320 cylindraceous clamps, tension force is relaxed; Extract from coiling frame 1311; Make core 560, so, can make core easily by enough simple equipment.

The stereogram of the core of as above-mentioned, making 560 is illustrated among Figure 21.In Figure 21; First (organic) fiber assembly 1K of the first grey cloth reel 1305 (upside reel) (for example; First (organic) fiber assembly 1Ka, 1Kb, 1Kc, 1Kd, 1Ke) and the 3rd fiber assembly 1, the 1J (downside fiber assembly) of the 3rd grey cloth roller 1307 (downside reel) under the state of having arranged five grey cloth reels across specified gap XK at width direction, be wrapped on the coiling frame 1311, twined continuously laterally from the inboard and by lamination.Because core 560 is in the sheet face approximate right angle direction combination with respect to fiber assembly 1,1J; Will be as first fiber assembly of fiber assembly overlapping and be wound on the outside of the 3rd single fiber assembly; So; Outer surface at core 560 constitutes a plurality of first (organic) fiber assembly 1Ka, 1Kb, 1Kc, 1Kd, 1Ke as first fiber assembly of conjugate fiber aggregate at width direction across gap (can be micro-gap, also can be specified gap) alignment arrangements.

Here; Though the width of width and first (organic) the fiber assembly 1K of the 3rd fiber assembly roughly is equal to; But, also can be shown in figure 21, make the width of the 3rd fiber assembly bigger than the width of first (organic) fiber assembly 1K; The mode that can access the specified gap of length X T (for example, XTa, XTe) amount with the width direction outside at first (organic) fiber assembly 1K disposes first (organic) fiber assembly 1K.If configuration by this way, distolateral at least one side of the width direction of the 3rd fiber assembly then do not have first (organic) fiber assembly 1K in the part of length X T, therefore, in the part of length X T, only has the 3rd fiber assembly.

Therefore; In that first (organic) fiber assembly 1K and the 3rd fiber assembly is overlapping; From inside to outside reel, when being configured as planar, there is not the core 560 of first (organic) fiber assembly 1K in the part that is manufactured on the distolateral length X T of at least one side's width direction.In view of the above; With first (organic) fiber assembly 1K and the 3rd fiber assembly by overlapping, from inside to outside reel, be configured as flat core and insert in the outer packaging material 4; Under the state that has reduced pressure with outer packaging material 4 sealings; Made under the situation of vacuum insulation material 760, same with vacuum insulation material 750 shown in Figure 19, vacuum insulation material 760 has thinner wall section H1, a H2 in that width direction is distolateral.In this case, length and the XTa of thinner wall section H1 roughly are equal to, and length and the XTe of thinner wall section H2 roughly are equal to, and the width H3 of middle body and the width of the first fiber assembly 1K roughly are equal to.Though thinner wall section can be arranged on the width direction both end sides of vacuum insulation material 760, the width direction that also can be arranged at least one side is distolateral.

Promptly; Because the width of at least the three fiber assembly than the width of first (organic) fiber assembly 1K go out greatly in first (organic) fiber assembly 1K between the end of the width direction of the width direction that be configured in width direction both end sides distolateral first (organic) fiber assembly 1Ka, 1Ke and three fiber assembly of width direction in a plurality of first (organic) fiber assembly 1Ka that specified gap XK arranges in abutting connection with ground, 1Kb, 1Kc, 1Kd, 1Ke length X T (for example; Among Figure 43; Side's in two width direction ends of the 3rd fiber assembly width direction end and as the length X Ta of the end of a side's of the 3rd fiber assembly of first (organic) fiber assembly 1Ka of the distolateral fiber assembly of width direction width direction tip side, or the opposing party's of the 3rd fiber assembly width direction end and as the length X Te of the end of the opposing party's of the 3rd fiber assembly of first (organic) fiber assembly 1Ke of the distolateral fiber assembly of width direction width direction tip side) amount; So; Vacuum insulation material 760 is same with vacuum insulation material 750, can be at a side's of width direction the distolateral thinner wall section H1 (perhaps H2) that obtains at least.

Promptly; Vacuum insulation material 750,760 has predetermined thickness t under the state that core 550,560 is depressurized and is closed in the packaging material 4 outside, the sectional shape of the width direction of the width direction end of core 550,560 is the end difference shape (thinner wall section H1 or H2) to the outstanding thin-walled in the width direction outside.

As stated; Even because vacuum insulation material 750,760 is not carried out special processing etc., also can obtain the thickness thinner wall section (H1 in Figure 19, H2) thinner in a side's of the width direction of core 550,560 distolateral or width direction both end sides than the thickness (thickness t of core 5,550,560) of vacuum insulation material 750,760, so; Situation a vacuum insulation material 750,760 being bent into drum is inferior; The end face of width direction (thinner wall section (H1, H2)) is overlapping at thickness direction each other making, and vacuum insulation material 750,760 is connected under the situation about using, makes the width direction end face (thinner wall section) of plural a plurality of vacuum insulation material 750,760 overlapping at thickness direction each other, under the situation about using continuously; If the surface of the thickness direction of the thinner wall section of the end face of the width direction of a plurality of vacuum insulation materials 750,760 is overlapping with the mode of contact each other; Then can there be the part contact of core 550,560, and, the thinner wall section of thin thickness is (overlapping at two; Under the situation that is staggered; Thickness is about half the) overlapping, therefore, can reduce the bond thickness of contact segment; And can reduce heat leak from contact segment, can access high performance vacuum insulation material 750,760, carry the machine such as compressor, refrigerator, hot-warer supplying machine of vacuum insulation material 750,760.

In addition; Because the sectional shape with width direction approximate right angle end face cross section on the length direction of a plurality of vacuum insulation materials 7,700,701,750,760 is towards the length direction outside; The general triangular shape of less thick; So the mode that contacts with each other as if the chamfered portion (chamfered portion of the length L 2 of Figure 11) with the general triangular shape connects, then the part contact of core 550,560 can be had; And can reduce the bond thickness of contact segment; And, can reduce heat leak from contact segment, can access high performance vacuum insulation material 7,700,701,750,760, carry the machines such as refrigerator of vacuum insulation material 7,700,701,750,760.

Here, with regard to the shape of length direction end, also can not that organic fiber aggregate 1, continuous sheet fiber assembly 1J are continuous at length direction, so long as be that the sectional shape of general triangular shape gets final product under by the state of lamination at fiber assembly.Promptly; So long as under with the state that the inside core 5,550,560 of packaging material 4 is depressurized outside, sealed; Have in the vacuum insulation material 7,700,701,750,760 of thickness t of width H and regulation of length L and regulation of regulation; Core 5,550,560 is made up of the stromatolithic structure of organic fiber aggregate 1, continuous sheet fiber assembly 1J, is that the cross section of end of at least a portion of length direction or width direction is that the general triangular shape that thickness diminishes toward the outer side gets final product.In addition; If core the 5,550, the 560th has the width H of regulation and the stromatolithic structure of from inside to outside reeling continuously at the continuous sheet organic fiber aggregate 1 of length direction, continuous sheet fiber assembly 1J; Under the state outside core 5,550,560 is sealed in the packaging material 4; The length direction end of core 5,550,560 is the general triangular shape, then can access same effect.

In addition, in the thinner wall section shape (the outstanding shape of thin-walled) of width direction, also can be that organic fiber aggregate 1, continuous sheet fiber assembly 1J are not continuous at length direction, can also be with the fiber assembly lamination of a plurality of length L.Promptly; As long as under with the state that the inside core 5,550,560 of packaging material 4 is depressurized outside, sealed; And have in the vacuum insulation material 7,700,701,750,760 of thickness t of width H and regulation of length L and regulation of regulation; As long as have thinner wall section 750a, the 750b of thin thickness in the end arbitrarily of length direction or width direction, thinner wall section 750a, 750b are outstanding laterally to get final product.In addition; If core the 5,550, the 560th, the organic fiber aggregate 1, continuous sheet fiber assembly 1J of a plurality of sheet of width H with regulation with overlap condition by the stromatolithic structure of lamination; thinner wall section 750a then can access the effect that is equal to through at least one a plurality of formation of state lamination with the established amount that staggered at width direction among a plurality of organic fiber aggregate 1, the continuous sheet fiber assembly 1J.

According to above-mentioned situation; The vacuum insulation material the 750, the 760th of this mode of execution has the planar of predetermined thickness, and the sectional shape of a flat direction (for example, length direction) end is towards foreign side; The general triangular shape of less thick; Perhaps the sectional shape of other direction (for example, width direction) end is made the end difference shape of the thinner wall section with thin thickness, therefore; Simple method overlapping through only carrying out, that twine can be made core 550,560 easily, can effectively utilize the end material.

In addition, even, also can end shape be made attachable shape because do not implement special processing etc. at length direction, width direction; So; If make end contact and connection, then can reduce the bond thickness of contact segment, and; Can reduce heat leak, can access high performance vacuum insulation material 750,760, carry the machine such as compressor, refrigerator, hot-warer supplying machine of vacuum insulation material 750,760 from contact segment.

Here; Core 560 is because same with core 5, core 550 shown in Figure 9, by two gripping memberss 1320 with the state that two positions clamp, make two gripping memberss 1320 in the opposite direction (direction of leaving) move; So; In clamped part, fiber assembly is manufactured into planar in bent end 560f folding (by bending).Same with core 5 shown in Figure 9 at core 560 as the folding core 560 of the bent end 560f of the end of length direction; From fiber assembly 1,1J; The coiling direction upstream side 560fa side of 1K is inserted in the opening portion 4a of outer packaging material 4; The state that is depressurized in inside is closed, and accomplishes vacuum insulation material 760.

Figure 22 representes to be folded into the sectional shape of the width direction of flat core 560; Core 560 is continuous at length direction laterally from the inboard; And single fiber assembly 1,1J and continuous at length direction at the also continuous width direction of width direction; And a plurality of first (organic) fiber assembly 1K that is split into a plurality of width directions at width direction with sheet face approximate right angle direction overlapping state under twined continuously, be folded into planar.And; Because width direction continuously and the single fiber assembly 1 of width direction, 1J to become inboard mode overlapping to compare with first (organic) fiber assembly 1K that has arranged a plurality of fiber assemblies at width direction; Be wound in coiled type from the inboard; So the mode that is created in the outer surface of core 560 with first (organic) fiber assembly 1K (first (organic) fiber assembly 1Ka, 1Kb, 1Kc, 1Kd, 1Ke) is reeled.At this moment, between each first (organic) fiber assembly 1Ka of first (organic) fiber assembly 1K, 1Kb, 1Kc, 1Kd, 1Ke, set specified gap XK for, form slit portion 560K (the 3rd slit portion).Specified gap XK is each specified gap XKab, XKbc, XKcd, XKde, and this each specified gap XKab, XKbc, XKcd, XKde can be identical, also can be different.

Figure 23 representes that core 560 is inserted into the inside of outer packaging material 4, and under the state that is depressurized in inside, the opening portion 4a of outer packaging material 4 is closed, by hermetically sealed vacuum insulation material 760.On vacuum insulation material 760; Length direction continuously and width direction be provided with a plurality of be arranged on the depressed part 760x (slot part that specified gap XK on the core 560 roughly is equal to width at width direction; For example, the first depressed part 760x1, the second depressed part 760x2; The 3rd depressed part 760x3, the 4th depressed part 760x4).Here, the width of the first depressed part 760x1, the second depressed part 760x2, the 3rd depressed part 760x3, the 4th depressed part 760x4 can be identical, also can be different, need only suitably settings such as size according to pipe arrangement.

Here, because specified gap XK is continuous at the coiling direction (length direction) of core 560, so; If use core 560; Make vacuum insulation material 760, then so that roughly to be equal to width continuous at length direction with specified gap XK, the degree of depth be about 1/4 the depressed part 560X (slot part) of thickness of vacuum insulation material 760 in the both sides of the platen surface of flat vacuum insulation material 760 (if the cup depth of the depressed part of both sides is added up to; Then be the degree of depth of pact half the (about 1/2) of the thickness of vacuum insulation material 760) produce; Therefore, through in this depressed part, disposing at least a portion of pipe arrangement (for example, condensation tube, suction pipe arrangement, discharge pipe arrangement etc.), guide line etc.; Even do not use other parts, also can carry out the taking in of heat insulation, guide line of pipe arrangement easily.In addition, because the location of pipe arrangement, guide line etc. can also position only through being configured in the depressed part 760x simultaneously, so, other parts that need not be used to locate, operation property also significantly improves.In addition, the recess of bending needn't be provided for separately through laser beam machining etc., also depressed part 760x bending easily can be passed through.

That kind as described above; Because the manufacturing installation of vacuum insulation material of the present invention possesses with the cut-out member that the organic fiber aggregate 1 of the width with regulation on the grey cloth reel 1301 that is wrapped in the general cylindrical shape shape that is cut into Rack, continuous sheet fiber assembly 1J have twined the coiling frame 1311 of the amount of stipulated number R, will be wrapped in organic fiber aggregate 1 on the coiling frame 1311, continuous sheet fiber assembly 1J cuts off, after the amount that will be wrapped in stipulated number R on the coiling frame 1311 and cut organic fiber aggregate 1, continuous sheet fiber assembly 1J extract from coiling frame 1311; The molded component that organic fiber aggregate 1, continuous sheet fiber assembly 1J are configured as flat core 5,550,560 (for example; Gripping members 1320); So; Can change places with simple light in structure and make core 5,550,560, can also shorten manufacturing time.In addition, owing to reel continuously at coiling direction, so, there is no need the cutting of length direction end face, because use at width direction, do not need cutting by pre-cut grey cloth reel yet, so, there is no need to cut core 5,550,560.In addition, also need not be used to cut the manufacturing equipment of the end face of core 5,550,560, the time that need not cut, therefore, can also make manufacturing equipment cheap, obtain core 5,550,560, vacuum insulation material 7,702,750,760 cheaply.In addition, through main part (fiber assembly) combination, can make the core 5,550,560 of big width with the grey cloth reel of a plurality of little width.In addition; Because through the quantity of suitably selected a plurality of grey cloth reels, the width of a plurality of grey cloth reels; Can not receive the width of grey cloth reel freely to set the width of core 5,550,560, so the degree of freedom in design of core 5,550,560 increases with influencing.In addition, because can make the big core 5,550,560 of width, so the site of storage of grey cloth reel is little to get final product, and does not need big site of storage from the little grey cloth warp tube of width.In addition, there is no need, in addition, also there is no need many ground laminations in order a plurality of fiber assembly laminations specially to be cut into each the size of regulation.In addition, and the sheet parts of continuous band shape are alternately turned back in different directions, make folding line and carry out overlapping mode lamination, the situation that forms core is compared, and does not need the device of making folding line and turning back of high price etc.Therefore, do not need laminating apparatus etc., the manufacturing of core 5,550,560 can be made core 5,550,560 in the short time easily through the simple equipment that only continuous sheet fiber assembly 1J is twined.

In addition; Because possessing coiling frame 1311, the manufacturing installation of vacuum insulation material 7,702,750,760 of the present invention is split into a plurality of circumference parts 1312; Make in a plurality of circumference parts 1312 at least one (for example; Circumference parts 1312a, 1312b that can be movable) movable in rotating center (running shaft 1315) direction, after organic fiber aggregate 1, continuous sheet fiber assembly 1J are wound onto coiling frame 1311, make can be movable circumference parts 1312a, 1312b turn round in the rotating center direction; The tension force of organic fiber aggregate 1, continuous sheet fiber assembly 1J is relaxed; Organic fiber aggregate 1, continuous sheet fiber assembly 1J are extracted from coiling frame 1311, so, will with the regulation tension force; After the tension force that for example is wrapped in the continuous sheet fiber assembly 1J on the coiling frame 1311 relaxes roughly cylindricly, can be with being extracted from coiling frame 1311 easily by the continuous sheet fiber assembly 1J of roughly cylindric winding.That is, relax through the tension force that will be wrapped in the continuous sheet fiber assembly 1J on the coiling frame 1311 with the tension force of regulation, the continuous sheet fiber assembly 1J that will be wrapped in easily on the coiling frame 1311 extracts from coiling frame 1311.

In addition; Because the manufacturing installation of vacuum insulation material 7,702,750,760 of the present invention is under the situation that organic fiber aggregate 1, continuous sheet fiber assembly 1J are extracted from coiling frame 1311; Extract by gripping members 1320 clampings; So, can change places with simple light in structure and organic fiber aggregate 1, continuous sheet fiber assembly 1J extracted from coiling frame 1311.In addition; If can use two gripping memberss 1320 (gripping members 1320c, 1320d); Keep the state that continuous sheet fiber assembly 1J has been clamped at two positions; Make two gripping members 1320c, 1320d movable or move at straight line side direction in the opposite direction (roughly 180 degree opposite directions) roughly; Then repeatedly twined and pulled in the opposite direction by two gripping members 1320c, 1320d by a plurality of continuous sheet fiber assembly 1J of lamination; Be formed from the planar of clamped part bending, therefore, can enough simple equipment form easily that continuous sheet fiber assembly 1J reels from the inboard laterally continuously and by the flat core 5,550,560 of lamination multilayer.

In addition; Production method according to vacuum insulation material 7,702,750,760 of the present invention; Because the continuous sheet fiber assembly 1J that possesses the width that is twined on the grey cloth reel 1301 with the general cylindrical shape that is cut into Rack with regulation to coiling frame 1311 twine the amount of stipulated number R winding step, will be wrapped in cut-out step that the continuous sheet fiber assembly 1J on the coiling frame 1311 cuts off, will have been twined the amount of stipulated number R and separating step that cut continuous sheet fiber assembly 1J extracts from coiling frame 1311 to coiling frame 1311, will be configured as at the continuous sheet fiber assembly 1J that separating step is extracted from coiling frame 1311 flat core 5,550,560 forming step, take in core 5,550,560 in the inside of outer packaging material 4 with airbond property; With inner pressure relief state under the outer packaging material sealing step of sealing; So, can make core 5,550,560 in the short time with simple method.In addition, owing to reel continuously at coiling direction, so, there is no need the cutting of length direction end face, because use at width direction also by pre-cut grey cloth reel, so, do not need cutting, therefore, there is no need to cut core 5,550,560.Therefore, because need not be used for manufacturing equipment with the end face cutting of core 5,550,560 yet, the time that also need not cut, so, can access core 5,550,560, vacuum insulation material 7,702,750,760 cheaply.

In addition; Production method according to vacuum insulation material 7,702,750,760 of the present invention; Because the clamping step that separating step is clamped by amount that will be wrapped in stipulated number R on the coiling frame 1311 with gripping members and cut continuous sheet fiber assembly 1J, will relax step at the fiber assembly tension force that the tension force with respect to coiling frame 1311 that clamps the clamped continuous sheet fiber assembly 1J of step relax, will relax coiling frame that continuous sheet fiber assembly 1J that step tension force relaxed extracts from coiling frame 1311 at tension force and remove step and constitute; So, can from coiling frame 1311 continuous sheet fiber assembly 1J be extracted easily with simple method.

In addition, according to the production method of vacuum insulation material 7,702,750,760 of the present invention, because forming step is used two gripping memberss 1320 (gripping members 1320c, 1320d); Continuous sheet fiber assembly 1J is clamped at two positions; Make two gripping memberss (gripping members 1320c, 1320d), core is configured as planar in that roughly opposite direction is movable, so; Through only using the simple method of gripping members 1320, can make the core 550 of sheet easily.

In addition; Because be the parts that the continuous continuous organic fiber of sheet fiber assembly 1J formed sheet; So; Compare as the situation of the glass fibre of inorfil with use, can suppress the harmful effect of dust human body, can also good core 550, the vacuum insulation material 7,702,750,760 of being reused property.

In this mode of execution; Also can be that fiber uses continuous organic fiber 2; Use organic fiber aggregate 1, continuous sheet fiber assembly 1J, twine to the coiling frame continuously laterally, make manufacturing installation, the production method of core 5,550,560, vacuum insulation material 7,702,750,760 etc. from the inboard; In the manufacturing installation of this mode of execution, production method, employed fiber also can not be continuous long fibre.Here, as long as fiber assembly is continuous sheet, as long as with the tension force of regulation during to 1311 windings of coiling frame, continuous sheet fiber assembly 1J can breakage etc. get final product.Therefore, also can not organic fiber aggregate 1, continuous sheet fiber assembly 1J, also can be the inorfil aggregate.In the manufacturing installation of this mode of execution, production method, if the fiber assembly of continuous sheet then can be brought into play same effect.In addition, though also can former state use the fiber assembly of continuous sheet,, then easy to manufacture if because the fiber assembly of continuous sheet is wound onto the state of the grey cloth reel on the grey cloth roller, and the property handled raising, so better.

Here, with organic fiber aggregate 1, continuous sheet fiber assembly 1J is overlapping and twine, and makes under the situation of core 550, also can not twine superimposedly and make core with established amount Xb.If the overlapping number of organic fiber aggregate 1, continuous sheet fiber assembly 1J is increased, the amount of number that then can the kind change of fiber assembly is overlapping.Promptly; Can use the different fiber assembly of weight per unit area of fiber assembly; Or the diverse fiber assembly that makes the fiber that uses in the fiber assembly (for example; The different fiber in the fiber that temperature characteristic is different, fiber footpath, pull the good fiber of intensity, the fiber that the pyroconductivity characteristic is different etc.) mix with the Environmental Conditions of machine with matching, therefore, core, the vacuum insulation material that can access and use form to match.Therefore, can take into account guaranteeing with high temperature endurance, taking into account guaranteeing and avoiding harmful effect, the raising of usability again of heat-shielding performance of heat-shielding performance to human body.In this case,, also there is no need the established amount Xb that staggers, therefore,, form core 5 and get final product as long as with the fiber assembly of same widths overlapping winding of pretty good turning up the soil even many fiber assemblies are overlapping.In addition, also can overlapping winding of the fiber assembly of different in width be formed core 5.

Here; Under the situation of the heat insulation vacuum insulation material of the machine that has high-temperature portion (for example more than 70 ℃) for the heat storage tank of the hot-warer supplying machine that need be used for high-temperature heat-storage water, compressor etc. with the part that becomes high temperature, if will have high temperature endurance (heat resistance) fiber (as the LCP of organic fiber, PPS or as the glass fibre of inorfil etc. separately or the fiber that has made up) be used at least one fiber.In this case, the mode of the surface side in the time of will having used the fiber assembly of the fiber with high temperature endurance (heat resistance) to form core to be configured in is overlapping, makes vacuum insulation material and gets final product.If because like this; Then as vacuum insulation material; Used the fiber assembly of fiber with high temperature endurance (heat resistance) in the surface side configuration; So,, then can have machine heat insulation of high-temperature portion if the mode that is configured in the high-temperature portion side of machine with the fiber assembly that has used the fiber with high temperature endurance (heat resistance) is provided with vacuum insulation material.

In addition; Under situation for the heat insulation vacuum insulation material of the machines such as refrigerator, heat insulating box etc. that are used for the high heat-shielding performance of requirement; Because require heat-shielding performance, so, as long as the solid thermal conductivity is little; The fiber (for example, as the polystyrene of organic fiber, as glass fibre of inorfil etc.) that can expect to improve heat-shielding performance is used at least one fiber and gets final product.

In addition, under situation, if use glass fibre as inorfil for the heat insulation vacuum insulation material of the machines such as refrigerator, air conditioner, hot-warer supplying machine that require again usability; Then for example in refrigerator, because utilizing factory to pulverize again by each goods, so; Glass fibre is entrained in polyurethane bits etc., supplies with heat and utilizes, still; Because glass fibre makes combustion efficiency reduce or become residue etc.; Usability is bad again, so, as long as use organic fibers such as polyester, polystyrene, LCP.

In addition, even considering under environmental problem, the dysgenic situation to human body, because glass fibre is hard and crisp; So, when the manufacturing of vacuum insulation material, when disintegrating, if dust disperses; Then there is the possibility that is upset in mucocutaneous etc. attached to the operator, and its property handled, operation property become problem; Therefore, also be to use organic fiber for well.
